s390/scm: Make struct scm_driver::remove return void
The driver core ignores the return value of scmdev_remove()
(because there is only little it can do when a device disappears).
So make it impossible for future drivers to return an unused error code
by changing the remove prototype to return void.
The real motivation for this change is the quest to make struct
bus_type::remove return void, too.
