I couldn't quite work out exactly why, but it seems to be a side-effect of the way we test that the NBD server is up: https://github.com/libguestfs/virt-p2v/blob/c1a4bd83a8bba5959470ef1f6deb0... I believe after your simplifications that code is not necessary at all, since with systemd socket activation the sockets passed to the server are always listening (even if the server isn't ready to accept a connection at that moment). Does it work OK if you simply remove wait_for_nbd_server_to_start and the place where that function is called?
