Oleg Nesterov eaf9ef5224 sched/wait: Avoid abort_exclusive_wait() in __wait_on_bit_lock() 
__wait_on_bit_lock() doesn't need abort_exclusive_wait() too. Right
now it can't use prepare_to_wait_event() (see the next change), but
it can do the additional finish_wait() if action() fails.

abort_exclusive_wait() no longer has callers, remove it.
