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 receivers that return no progress so it can keep

Tested with a modified version of vp_vdpa to fail negotiation.

* Replace dummy receive_{iov,raw} with receive callback.
* Delete fix indentation commit, we don't touch that code anymore.
