Controller: Always send ADDRMAP event after RESOLVE command (#8596 part 1/2)

Since 7536c40 only DNS results for real SOCKS requests are added to the cache,
but not DNS results for DNSPort queries or control connection RESOLVE queries.
Only cache additions would trigger ADDRMAP events on successful resolve.

Change it so that DNS results received after a RESOLVE command also generate
ADDRMAP events.
