Log message:
Fix for bz #426291. gfs_glock_dq was traversing the gl_holders list without
holding the gl_spin spinlock, this was causing a problem when the list item
it was currently looking at got removed from the list. The solution is to
not traverse the list, because it is unncessary. Unfortunately, there is also
a bug in this section of code, where you can't guarantee that you will not
cache a glock held with GL_NOCACHE. Fixing this issue requires significantly
more work.
