AFS: fix file locking

Fix file locking for AFS:

 (*) Start the lock manager thread under a mutex to avoid a race.

 (*) Made the locking non-fair: New readlocks will jump pending writelocks if
     there's a readlock currently granted on a file.  This makes the behaviour
     similar to Linux's VFS locking.
