USB: make to_usb_device_driver() use container_of_const()
Turns out that we have some const pointers being passed to
to_usb_device_driver() but were not catching this. Change the macro to
properly propagate the const-ness of the pointer so that we will notice
when we try to write to memory that we shouldn't be writing to.
This requires fixing up the usb_driver_applicable() function as well,
because it can handle a const * to struct usb_driver.
