GFS2: Review bug traps in glops.c
Two of the bug traps here could really be warnings. The others are converted from BUG() to GLOCK_BUG_ON() since we'll most likely need to know the glock state in order to debug any issues which arise. As a result of this, __dump_glock has to be renamed and is no longer static. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
