virtio-scsi: define dummy handle_output for vhost-scsi vqs
vhost userspace needn't to handle vq's notification from guest,
so define dummy handle_output callback for all vqs of vhost-scsi.
In some corner cases(such as when handling vq's reset from VM), virtio-pci
still trys to handle pending virtio-scsi events, then object check failure
inside virtio_scsi_handle_event() for vhost-scsi can be triggered.
The issue can be reproduced by 'rmmod virtio-scsi', 'system sleep' or reboot
inside VM.
