ALSA: usb-audio: Add helper function for volume range checks

Browse source

When a potentially insane volume range is found, the volume control
parameters will be printed in WARN level instead of DEBUG level.
Currently, it's done by emitting a open-coded usb_audio_warn() in the
corresponding check.

The following changes are about to add more checks against volumen
ranges. As the first step, extract the current check logic into a helper
function to improve readability.

No functional change intended.
