[PATCH 4/3] rtmutex: Avoid barrier in rt_mutex_handle_deadlock

[Davidlohr Bueso]

The very nature of rt_mutex_handle_deadlock() implies that this
patch is merely a formality, as in practice the saved barrier
is of little use. That said, we can relax setting the task state
and be done with it; blocking unconditionally... this is a deadlock!
