[PATCH iproute2 v1 1/1] lib/utils: fix get_addr() and get_prefix() error messages

[Varlese, Marco]

An attempt to add invalid address to interface would print "???" string
instead of the address family name.

For example:
$ ip address add 256.10.166.1/24 dev ens8
Error: ??? prefix is expected rather than "256.10.166.1/24".

$ ip neighbor add proxy 2001:db8::g dev ens8
Error: ??? address is expected rather than "2001:db8::g".

With this patch the output will look like:
$ ip address add 256.10.166.1/24 dev ens8
Error: inet prefix is expected rather than "256.10.166.1/24".

$ ip neighbor add proxy 2001:db8::g dev ens8
Error: inet6 address is expected rather than "2001:db8::g".
