James Smart 27f344eb15 lpfc: Add iotag memory barrier
Add a memory barrier to ensure the valid bit is read before
any of the cqe payload is read. This fixes an issue seen
on Power where the cqe payload was getting loaded before
the valid bit. When this occurred, we saw an iotag out of
range error when a command completed, but since the iotag
looked invalid the command didn't get completed to scsi core.
Later we hit the command timeout, attempted to abort the command,
then waited for the aborted command to get returned. Since the
adapter already returned the command, we timeout waiting,
and end up escalating EEH all the way to host reset. This
patch fixes this issue.

James Smart 53151bbb83 [SCSI] lpfc 8.3.43: Fixed not processing task management IOCB response status
This patch implements the changes requested by Jeremy Linton:
http://marc.info/?l=linux-scsi&m=136242124409687&w=2

The patch revises the command issuing behavior, detecting cases where the
Task Mgmt command may have completed but with a non-successful status, which it
previously treated as a successful TMF. The patch also corrects a flushing of
I/O that was done which should only be done on successful TMF completion.
