monitor_qmp_dispatcher_co() needs to resume the monitor if
handle_qmp_command() suspended it. Two cases:
1. OOB enabled: suspended if mon->qmp_requests has no more space
2. OOB disabled: suspended always
We resume only after we processed the request. Which can take a long
time.
Resume the monitor right when the queue has space to keep the monitor
available for out-of-band commands even in this corner case.
Leave the "OOB disabled" case alone.
