usb: gadget: move the global the_dev variable to their users
the u_ether.c file has a global variable named the_dev which keeps a
pointer to the network device after it has been created via
gether_setup_name(). It is only used internally by u_ether. This patches
moves the variable to its users and passes it via the port.ioport where
it is saved later anyway.
