media: uvcvideo: Fix InterfaceProtocol for Quanta camera
The Quanta 0408:4034 camera implements UVC 1.5, and thus sets
bInterfaceProtocol to UVC_PC_PROTOCOL_15. Commit 95f03d973478 ("media:
uvcvideo: Limit power line control for Quanta cameras") added a quirk
for the device that incorrectly specified the UVC 1.0 protocol,
rendering the quirk inoperative. Fix it.
