usb: gadget: rndis: init & exit rndis at module load/unload
This is required in preparation for using usb_gstrings_attach.
The rndis initialization so far has been performed on the first
occurence of rndis_bind(), but the condition to check it (first
or not first) was "borrowed" from strings handling.
