[PATCH 11/19] staging: lustre: remove back_to_sleep()

When 'back_to_sleep()' is passed as the 'timeout' function, the effect is to wait indefinitely for the event, polling once after the timeout. If LWI_ON_SIGNAL_NOOP is given, then after the timeout we allow fatal signals to interrupt the wait. Make this more obvious in both places "back_to_sleep()"
