Adds a missing check for an error return code from scsi_sysfs_add_sdev.
This resolves entry #4863 in the OSDL bugzilla. Although in that bug
report the failure occurred because of a confusion over scanning vs.
rescanning, in general add_sdev can fail for a number of reasons (the
simplest being insufficient memory) and the caller should cope properly.

scsi_init_io calls scsi_alloc_sgtable and then calls blk_rq_map_sg
to initialize the scatterlist structure. blk_rq_map_sg() already
memset the structure for every new segment. That makes the memset
in scsi_alloc_sgtable unnecessary.
Patch to delete the extra memset in scsi_alloc_sgtable. Tested on
a x86_64 machine. Looks stable to me.

One of the issues we had was reverting the midlayers lun value
into the 8byte lun value that we wanted to send to the device.
Historically, there's been some combination of byte swapping,
setting high/low, etc. There's also been no common thread between
how our driver did it and others. I also got very confused as
to why byteswap routines were being used.
Anyway, this patch is a LLDD-callable function that reverts the
midlayer's lun value, stored in an int, to the 8-byte quantity
(note: this is not the real 8byte quantity, just the same amount
that scsilun_to_int() was able to convert and store originally).
This also solves the dilemma of the thread:
http://marc.theaimsgroup.com/?l=linux-kernel&m=112116767118981&w=2
A patch for the lpfc driver to use this function will be along
in a few days (batched with other patches).

Cleanup FC remote port registration.
Due to the inherent behaviour (an immediate scan) of adding
a 'target'-role-capable rport via fc_remote_port_add(),
split the registration into two steps -- addition as
unknown-type role, then use fc_remote_port_rolchg() with
appropriate role (based on PLOGI/PRLI bits). This allows
for a more cleaner rport->dd_data management as can be seen
with the simplified qla2xxx_slave_alloc() function.

One correction is needed. Changes are not needed for
drivers/scsi/pcmcia/nsp_cs.c because it uses versioning in the
compatibility part, which is never used in 2.6 kernels. The only right
thing we could to that compatibility code would be to remove it throughout
the file, but that would be a separate patch.

The Linux PCMCIA code has some data that was apparently used (or meant to be
used) to ensure that only proper client drivers are loaded. This is now
ensured (to a certain degree) by the fact that the most client drivers are
part of the kernel. Also, the version information has not been updated
despite major changes in PCMCIA API. This has made it meaningless.
This patch removes servinfo_t and pcmcia_get_card_services_info. They are not
used in any userspace utilities such as pcmcia-cs and pcmciautils.
drivers/pcmcia/pcmcia_ioctl.c is adjusted accordingly.
CS_RELEASE and CS_RELEASE_CODE are removed. include/pcmcia/version.h is empty
now. It will be removed later, but for now it's left in the tree to avoid
touching all PCMCIA clients.
The only driver that needs to be changed is drivers/scsi/pcmcia/nsp_cs.c,
which uses CS_RELEASE_CODE.
