Pull gfs2 updates from Andreas Gruenbacher:

 - Instantiate glocks ouside of the glock state engine, in the contect
   of the process taking the glock. This moves unnecessary complexity
   out of the core glock code. Clean up the instantiate logic to be more
   sensible.

 - In gfs2_glock_async_wait(), cancel pending locking request upon
   failure. Make sure all glocks are left in a consistent state.

 - Various other minor cleanups and fixes.
