driver(9): devsw_detach never fails. Make it return void.
Prune a whole lotta dead branches as a result of this. (Some logic calling this is also wrong for other reasons; devsw_detach is final -- you should never have any reason to decide to roll it back. To be cleaned up in subsequent commits...) XXX kernel ABI change to devsw_detach signature requires bump
