The existing p9_bind_privport() implementation is TCP-specific
(uses inet_pton and struct sockaddr_in), so it cannot be reused
for vsock directly. Per Stefan Hajnoczi's suggestion, I opted to
reject the option cleanly for now rather than leave it silently
ignored. Support can be added in a follow-up if needed.

I noticed it as I was adding the vsock line below, but you're right,
it's not related, so I'll drop it in v3.
