netconsole: show empty string for an unset IP address

Browse source

An unset address (local_ip/remote_ip), now denoted by AF_UNSPEC,
currently shows "0.0.0.0" in configfs. Print an empty string instead,
which is more clear.

In netconsole_print_banner() we can be even more explicit about it, as
we don't have the risk of userspace trying to parse it.
