futex: split out atomic logic from futex_lock_pi()
Refactor the atomic portion of futex_lock_pi() into futex_lock_pi_atomic().
This logic will be needed by requeue_pi, so modularize it to reduce
code duplication. The only significant change is passing of the task
to try and take the lock for. This simplifies the -EDEADLK test as if
the lock is owned by task t, it's a deadlock, regardless of if we are
doing requeue pi or not. This patch updates the corresponding comment
accordingly.
