Commit e66cf161 replaced the gl_spin spinlock in struct gfs2_glock with a
gl_lockref lockref and defined gl_spin as gl_lockref.lock (the spinlock in
gl_lockref). Remove that define to make the references to gl_lockref.lock more
obvious.

We recently added some glock statistics to GFS2, so this is
a docs update to explain what they all mean. It is based
upon the checkin comment of the patch in question.
