[GFS2] Fixes to scanning of glocks (again)
This really is the correct fix this time. We just ignore all
glocks associated with inodes until the inodes are pushed
from the inode cache. At that point the glocks are queued for
reclaim, so we don't need to do it here.
Also fix one or two other minor bugs.
