wifi: rt2x00usb: fix devres lifetime

USB drivers bind to USB interfaces and any device managed resources should have their lifetime tied to the interface rather than parent USB device. This avoids issues like memory leaks when drivers are unbound without their devices being physically disconnected (e.g. on probe deferral or configuration changes).

Fix the USB anchor lifetime so that it is released on driver unbind.
