audio: rework audio_bug()

Browse Source 
audio_bug() is a bit unconventional, it is meant to be used as a
condition expression, passing the actual condition as second argument
(and __func__ as first argument).

If the condition is true, it uses AUD_log() to print to stderr, and has
some dubious recommendations printed only once.

This change:
- clears the control flow, and make the condition directly visible in
  the 'if' statement.
- uses standard QEMU error_report()
- audio_bug() now captures __func__
- remove the "Save all your work and restart..." once hint
