Subject: [PATCH] ALSA: usb: Parse UAC2 extension unit like for UAC1

commit 61ac51301e6c6d4ed977d7674ce2b8e713619a9b upstream.

UAC2_EXTENSION_UNIT_V2 differs from UAC1_EXTENSION_UNIT, but can be handled in
the same way when parsing the unit. Otherwise parse_audio_unit() fails when it
sees an extension unit on a UAC2 device.

UAC2_EXTENSION_UNIT_V2 is outside the range allocated by UAC1.
