Miroslav Lichvar 08b67dba98 ntp: fix finalization for async resolver ...

If an attempt to resolve addresses of an NTP server is made right before
starting the termination sequence, the asynchronous resolver thread
could read the server name when it was already freed.

Leave unresolved sources allocated in NSR_Finalise() if the async
resolver did not finish yet, at least for now. Waiting for the resolving
result or cancelling the thread would complicate the code. The scheduler
is not expected to be running at this point.
