virtio: validate the existence of handle_output before calling it
We don't validate the existence of handle_output which may let a buggy
guest to trigger a SIGSEV easily. E.g:
1) write 10 to queue_sel to a virtio net device with only 1 queue
2) setup an arbitrary pfn
3) then notify queue 10
Fixing this by validating the existence of handle_output before.
