Remove ad-hoc handling of possible_out == 0

Browse source 
Just refuse configurations without any output at all, and let the
remaining logic take care of selecting configurations with no audio
output if they make sense and there are no better configurations.

POLICY CHANGE: configurations with no output might now be considered
even if they have audio inputs (e.g. a pure pitch detector without audio
passthrough), whereas they were skipped before.
