[Qemu-devel] [PATCH] [trivial] print meaningful error message in case of --disable-vhost-net |

When qemu gets compiled without support of vhost-net, any attempt
to use it fails with a very clear error message:
qemu-system-x86_64: -netdev ...,vhost=on: vhost-net requested but could not be
initialized
there's absolutely no reason given _why_ it coult not be
initialized, and even strace'ing the process in question
does not reveal any errors. So print a message telling
what's going on.
