dns: powerdns: correctly handle different records types (A / AAAA)

Browse source 
This fixes an issue with dual stacking, when using a zone with both a
IPv4 and IPv6 subnet and the same DNS suffix, pve-network will try to
set both DNS records (type A and AAAA) in the same powerdns rrset,
causing an API error, and effectively causing no forward DNS records
being created.

This change edits the `get_zone_rrset` function so that it takes the
DNS record type into account.
