audio: do not use first -audiodev as default audio device

Browse source 
It is now possible to specify the options for the default audio device
using -audio, so there is no need anymore to use a fake -audiodev option.

Remove the fall back to QTAILQ_FIRST(&audio_states), instead remember the
AudioState that was created from default_audiodevs and use that one.
