Message:

When answer_preprocess() wins the race for a call, let it also dequeue
the call from the sender's active list so that we have a real atomic
either-answered-or-forgotten behavior.

This change avoids the possibility that the race is won in
answer_preprocess(), but lost later in _ipc_answer_free_call(), which
would have the effect of skipping some of the necessary call_t cleanup.
