Revert "gfs2: fix glock shrinker ref issues"

Browse Source 
This reverts commit 62862485a4.

Commit 62862485a4 tried to fix issues introduced by commit
228804a35c ("gfs2: Make glock lru list scanning safer"), but like that
commit, it failed to account for the bias state_change() adds to the
glock reference count for locked glocks.  Revert commit 62862485a4 so
that we can fix commit 228804a35c properly.
