Oleg Nesterov d2ee7198cc pi-futex: set PF_EXITING without taking ->pi_lock ...

It is a bit annoying that do_exit() takes ->pi_lock to set PF_EXITING.  All
we need is to synchronize with lookup_pi_state() which saw this task
without PF_EXITING under ->pi_lock.

Change do_exit() to use spin_unlock_wait().
