Workaround for monitor bug related to greeting msg

QMP may return multiple greeting messages upon connection.
This is reported on qemu-devel. The fix is one-liner but
until it get's released this is a quick and dirty workaround
that flushes the client's buffer after getting the first
greeting message.
