USB: option: revert introduction of struct option_private
This is a partial, context modified revert of commit e463c6dda8f5
("USB: option: handle send_setup blacklisting at probe"), which
introduced an unnecessary struct option_private for storing the
interface number used in option_send_setup. Removing this struct
will allow option_send_setup to be generalized for other drivers.
