Fixed minor bug in resolving of IPv4 names if IPv6 is enabled (#0000659).

Browse Source 
We were doing: T_AAAA, if that fails then T_A. But in that case when a host
has both T_A and T_AAAA entries, the reverse lookup will fail for ipv4.
Now using T_ANY to fetch both T_A and T_AAAA addresses at once.
