ALSA: snd-usb: mixer: propagate errors up the call chain

commit 4d7b86c98e445b075c2c4c3757eb6d3d6efbe72e upstream.

In check_input_term() and parse_audio_feature_unit(), propagate the
error value that has been returned by a failing function instead of
-EINVAL. That helps cleaning up the error pathes in the mixer.
