Zhao Jianing fe9dffcd13 plugin/rewrite: Fixes a nil pointer dereference panic in ResponseReverter.WriteMsg (#8519) ...

ResponseReverter.WriteMsg calls res1.Copy() without checking res1 for
nil, so any plugin further down the chain that writes a nil response
(for example a handler returning (dns.RcodeSuccess, nil) after
w.WriteMsg(nil)) panics here.

Return an error instead, mirroring the nil guard recently added to
plugin/cache's ResponseWriter.WriteMsg (#8512).
