virtio-serial-bus: use bh for unthrottling
Instead of calling flush_queued_data when unthrottling, schedule
a bh. That way we can return immediately to the caller, and the
flush uses the same call path as a have_data for callbackee.
No migration change is required because bh are called from vm_stop.
