staging: fieldbus: anybus: Make remove callback return void
The driver core ignores the return value of struct bus_type::remove()
because there is only little that can be done. To simplify the quest to
make this function return void, let struct
anybuss_client_driver::remove() return void, too. All users already
unconditionally return 0, this commit makes it obvious that returning an
error code is a bad idea.
