Subject: [PATCH] futex: Fix bug in WARN_ON for NULL q.pi_state

commit f27071cb7fe3e1d37a9dbe6c0dfc5395cd40fa43 upstream.

The WARN_ON in futex_wait_requeue_pi() for a NULL q.pi_state was testing
the address (&q.pi_state) of the pointer instead of the value
(q.pi_state) of the pointer. Correct it accordingly.
