ACK.

This actually fixed a debug output that confused me. Before this patch
the output claimed

19:14:15.365: 2140: debug : virEventPollCalculateTimeout:345 : Timeout
at 0 due in 0 ms

But this 0 0 case is impossible from the logic in the code. After the
patch it is reporting correctly

20:15:25.157: 2140: debug : virEventPollCalculateTimeout:345 : Timeout
at 0 due in -1 ms
