[ Upstream commit 80df01f4dc79abbed724bbe0851cab3fe8ad9d99 ]
usb drivers are supposed to communicate using usb_interface instead
mt76x{0,2}u is now registering through usb_device. Fix it by passing
usb_intf device to mt76_alloc_device routine.
Fixes: 112f980ac8926 ("mt76usb: use usb_dev private data")
