03f50d7ee756eecbd4481c3008b5e01e999729c7 monitor: don't wake up qmp_dispatcher_co coroutine upon cleanup
Since the commit 3e6bed61 ("monitor: cleanup detection of qmp_dispatcher_co
shutting down"), coroutine pointer qmp_dispatcher_co is set to NULL upon
cleanup. If a QMP command is sent after monitor_cleanup() (e.g. after
shutdown), this may lead to SEGFAULT on aio_co_wake(NULL).
As mentioned in the comment inside monitor_cleanup(), the intention is to
allow incoming requests while shutting down, but simply leave them
without any response. Let's do exactly that, and if qmp_dispatcher_co
coroutine pointer has already been set to NULL, let's simply skip the
aio_co_wake() part.
