block: WARN in __blk_put_request() for potential bio leak
Put a WARN_ON in __blk_put_request if it is about to leak bio(s). This is a serious bug that can happen in error handling code paths. For this to work I have fixed a couple of places in block/ where request->bio != NULL ownership was not honored. And a small cleanup at sg_io() while at it.
