Fix some broken logic in the prefork MPM. Basically, in the past, if we

accepted a request, we didn't want to die if given a graceful restart
signal.  The logic I am removing stops us from dying for a graceless
restart/stop signal, which is just wrong.  If we are sent a graceless
restart/stop, then we need to stop immediately.
