Hmm, I'm not sure what this check was doing - if the address was succesfully
parsed in AddrIsNumeric, it should be parsed by virSocketAddrParse as well.

We also do this parsing to chceck for numeric IPv6 addresses in
qemuMigrationPrepareAny. It would be nicer to create a new
'virSocketAddrIsNumericIPv6' function and use it in both of them.
