mmdevice: only use active devices

Multimedia / VLC - Jean-Baptiste Kempf [videolan.org] - 30 June 2016 06:40 UTC

This fixes a crash (a Windows Exception) when VLC is run just after windows start and when an unactive device is activated.

This issue is very hard to reproduce, here is the backtrace:
