[GFS2] Fix a ref count bug and other clean ups
This fixes a ref count bug that sometimes showed up a umount time (causing it to hang) but it otherwise mostly harmless. At the same time there are some clean ups including making the log operations structures const, moving a memory allocation so that its not done in the fast path of checking to see if there is an outstanding transaction related to a particular glock. Removes the sd_log_wrap varaible which was updated, but never actually used anywhere. Updates the gfs2 ioctl() to run without the kernel lock (which it never needed anyway). Removes the "invalidate inodes" loop from GFS2's put_super routine. This is done in kill super anyway so we don't need to do it here. The loop was also bogus in that if there are any inodes "stuck" at this point its a bug and we need to know about it rather than hide it by hanging forever.
