This patch fixes code readability and should have no functional change.
Correct uac control query functions to account for the 1-based indexing
of USB Audio Class control identifiers.
The function parameter, u8 control, should be the
constant defined in audio-v2.h to identify the control to be checked for
readability or writeability.
This patch fixes all callers that had adjusted, and makes explicit
the mapping between audio_feature_info[] array index and the associated
control identifier.
