hmp: convert handle_hmp_command() to AIO_WAIT_WHILE_UNLOCKED()

The HMP monitor runs in the main loop thread. Calling
AIO_WAIT_WHILE(qemu_get_aio_context(), ...) from the main loop thread is
equivalent to AIO_WAIT_WHILE_UNLOCKED(NULL, ...) because neither unlocks
the AioContext and the latter's assertion that we're in the main loop
succeeds.
