[GFS2] Fix change nlink deadlock
Bugzilla 215088
Fix deadlock in gfs2_change_nlink() while installing RHEL5 into GFS2
partition. The gfs2_rename() apparently needs block allocation for the
new name (into the directory) where it requires rg locks. At the same
time, while updating the nlink count for the replaced file,
gfs2_change_nlink() tries to return the inode meta-data back to resource
group where it needs rg locks too. Our logic doesn't allow process to
acquire these locks recursively by the same process (RHEL installer)
that results a BUG call. This only happens within rename code path and
only if the destination file exists before the rename operation.
