Eugenio Pérez 846a1e85da vdpa: Add dummy receive callback
Qemu falls back on userland handlers even if vhost-user and vhost-vdpa
cases. These assumes a tap device can handle the packets.

If a vdpa device fail to start, it can trigger a sigsegv because of
that. Add dummy receiver that returns no progress so it can keep
running.
