USB: make to_usb_driver() use container_of_const()

Turns out that we have some const pointers being passed to
to_usb_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_match_dynamic_id() function as well,
because it can handle a const * to struct usb_driver.
