Gang He 01a36b6758 ocfs2: ensure that dlm lockspace is created by kernel module 
We encountered a bug from the customer, the user did a fsck.ocfs2 on the
file system and exited unusually, the lockspace (with LVB size = 32) was
left in the kernel space, next, the user mounted this file system, the
kernel module did not create a new lockspace (LVB size = 64) via calling
dlm_new_lockspace() function in mounting stage, just used the existing
lockspace, created by the user space tool, this would lead the user was
not able to mount this file system from the other nodes, with the error
message like:

  dlm: 032F5......: config mismatch: 64,0 nodeid 177127961: 32,0
  (mount.ocfs2,26981,46):ocfs2_dlm_init:2995 ERROR: status = -71
  ocfs2_mount_volume:1881 ERROR: status = -71
  ocfs2_fill_super:1236 ERROR: status = -71

The user found it very difficult to find the root cause, then, we
brought out this patch to relieve such problem.

First, we add one more flag in calling dlm_new_lockspace() function, to
make sure the lockspace is created by kernel module itself, and this
change will not affect the backward compatibility.

Second, the obvious error message is reported in the kernel log, let the
user be more easy to find the root cause.

This patch will be used to insure the dlm lockspace is created by kernel
module when mounting a ocfs2 file system.  There are two ways to create
a lockspace, from user space and kernel space, but the same name
lockspaces probably have different lvblen lengths/flags.

To avoid this mix using, we add one more flag DLM_LSFL_NEWEXCL, it will
make sure the dlm lockspace is created by kernel module when mounting.
Secondly, if a user space program (ocfs2-tools) is running on a file
system, the user tries to mount this file system in the cluster, DLM
module will return a -EEXIST or -EPROTO errno, we should give the user a
obvious error message, then, the user can let that user space tool exit
before mounting the file system again.
