winecoreaudio.drv: Don't return 0 absolute position if AudioQueue call fails.

Some failures are temporary, for example if the user reconfigures their
audio setup while playing audio. Returning 0 could have bad "going
backward in time" effects which can break audio even after the call
starts to succeed again.
