Use NsdServiceInfo ifIndex in MdnsDiscoveryManager
NsdServiceInfo may contain an interface index if it was obtained from a
previous discovery callback which found a service on an interface that
does not belong to any Network.
In that case, subsequent resolve or registerServiceInfoCallback queries
using that NsdServiceInfo should only be done on the matching interface.
Apps may otherwise receive replies from other networks, with different
interface addresses.
As a simple fix, still request sockets from all interfaces in that case,
but only create the MdnsServiceTypeClients on matching sockets.
The sockets are created / cleaned up based on the lifecycle of the
requests, which does not change.
