From: "Daniel P. Berrange" <berra...@redhat.com>
The 'sun_path' field in the sockaddr_un struct is not required
to be NUL termianted, so when reporting an error, we must use
the separate 'path' variable which is guaranteed terminated.
Fixes a bug spotted by coverity that was introduced in
commit ad9579aaa16d5b385922d49edac2c96c79bcfb62
