ALSA: usb-audio: Add implicit feedback quirk for RODE AI-1

The RODE AI-1 audio interface requires implicit feedback sync between
playback endpoint 0x03 and feedback endpoint 0x84 on interface 3, but
doesn't advertise this in its USB descriptors.

Without this quirk, the device receives audio data but produces no output.
