BUG/MINOR: proto_tcp: Report warning messages when listeners are bound

When a TCP listener is bound, in the tcp_bind_listener() function, a warning
message may be reported and should be displayed on verbose mode. But the warning
message is actually lost if the socket is successfully bound because we don't
fill the <errmsg> variable in this case.

This patch should fix the issue #863. No backport is needed.
