[PATCH] pi-futex: fix mm_struct memory leak
lock_queue was getting called essentially twice in a row and was
continually incrementing the mm_count ref count, thus causing a memory
leak.
Dinakar Guniguntala provided a proper fix for the problem that simply grabs
the spinlock for the hash bucket queue rather than calling lock_queue.
The second time we do a queue_lock in futex_lock_pi, we really only need to
take the hash bucket lock.
