conncheck: Connection check reply must have a remote candidate

Ensure that a conncheck reply is coming from an address and port of a
known remote candidate and that the type of incoming socket matches that
candidate's transport.

Attemps to fix a Coverity issue in which no matching remote_candidate
gets found for a connectivity reply in conn_check_handle_inbound_stun()
(apparently due to transport mismatch), yet
priv_map_reply_to_conn_check_request() still successfully matches it
with a previous request.
