0e3b5d6a68 Take lock in pthread_cond_wait cleanup handler only when needed
[BZ #14652]
When a thread waiting in pthread_cond_wait with a PI mutex is
cancelled after it has returned successfully from the futex syscall
but just before async cancellation is disabled, it enters its
cancellation handler with the mutex held and simply calling a
mutex_lock again will result in a deadlock.  Hence, it is necessary to
see if the thread owns the lock and try to lock it only if it doesn't.
