unqueue_me - Remove the futex_q from its futex_hash_bucket
int unqueue_me(struct futex_q * q);
The q->lock_ptr must not be held by the caller. A call to unqueue_me must be paired with exactly one earlier call to queue_me.
1 - if the futex_q was still queued (and we removed unqueued it); 0 - if the futex_q was already removed by the waking thread
