USB: usb peripheral controller driver oops avoidance

I'm having problem with oopses when rebooting, if I modprobe g_serial
and rmmod g_serial and do a reboot I get an oops in device_shutdown().
The reason seems to be that usb_gadget_unregister_driver() doesn't do
enough cleanup.  With this at91_udc patch I don't get the oops.
