ALSA: usb-audio: Use correct sub-type for UAC3 feature unit validation

Browse source 
[ Upstream commit 8410fe81093ff231e964891e215b624dabb734b0 ]

The entry of the validators table for UAC3 feature unit is defined
with a wrong sub-type UAC_FEATURE (= 0x06) while it should have been
UAC3_FEATURE (= 0x07).  This patch corrects the entry value.
