ALSA: usb-audio: map UAC3 front wide channels in convert_chmap_v3()
convert_chmap_v3() translates UAC3 channel relationship values into
ALSA channel-map positions.
UAC3_CH_FRONT_WIDE_LEFT and UAC3_CH_FRONT_WIDE_RIGHT currently fall
back to SNDRV_CHMAP_UNKNOWN, although ALSA already provides matching
channel-map positions via SNDRV_CHMAP_FLW and SNDRV_CHMAP_FRW.
Map these two UAC3 positions to their ALSA equivalents and update the
comment to clarify that unsupported UAC3 channel relationships remain
reported as SNDRV_CHMAP_UNKNOWN.
No functional change for other channel relationships.
