[WIN] close/reopen the wasapi audio device when lost

This is an attempt to fix http://forum.xbmc.org/showthread.php?t=121689

The error code returned by WASAPI is clear, so chances are pretty good this fix works (ie release the device interfaces and recreate them later)

Unfortunately I am unable to repro the issue, and don't receive the error code when unplugging outputs or changing device parameters while paused.
