[GFS2] Reorganize function gfs2_glmutex_lock
This patch optimizes the function gfs2_glmutex_lock.
The basic theory is: Why bother initializing a holder, setting up
wait bits and then waiting on them, if you know the glock can be
yours. So the holder stuff is placed inside the if checking if the
glock is locked. This one needs careful scrutiny because changing
anything to do with locking should strike terror into one's heart.
