    Cache bypass: Fix oops in bypass transition functions
    
    The FCSBypass flag might change between the time we check it before
    entering afs_TransitionToCaching or afs_TransitionToBypass and when
    we check it again within the functions.
    
    Instead of panicing, just exit if someone beat us to it.  Also move
    the checks within the write lock region to make sure the code
    doesn't get run multiple times.
