wait: don't use __wake_up_common()
'777c6c5 wait: prevent exclusive waiter starvation' made
__wake_up_common() global to be used from abort_exclusive_wait().
It was needed to do a wake-up with the waitqueue lock held while
passing down a key to the wake-up function.
Since '4ede816 epoll keyed wakeups: add __wake_up_locked_key() and
__wake_up_sync_key()' there is an appropriate wrapper for this case:
__wake_up_locked_key().
Use it here and make __wake_up_common() private to the scheduler
again.
