Fixes #22575, as suggested by poettering in #35514. Intended as a workaround for some buggy routers, which refuse to send empty replies. If systemd-resolved starts two DnsTransactions, one for A and one for AAAA, and the domain in question has no AAAA entry, then the server will send a reply for A and no reply for AAAA. Correct behavior for the server would be to send an empty reply for AAAA. systemd-resolved would previously keep retrying the AAAA transaction, and eventually timeout the whole query, returning an error to the caller. Now, if the server replies to one query and not another, we cut short the timeout and return the partial result. Returning the partial result allows the rest of the system to keep working. It matches how e.g. glibc libnss_dns behaves.
