staging: gasket: gasket_wait_with_reschedule simplify logic

gasket_wait_with_reschedule() is a little more clear if we just return
directly when the waited-for condition is hit.  This also allows the
following condition check to be removed and identation of the
conditionally-executed code to be reduced.
