blockdev: Remove 'type' parameter from blockdev_init()
blockdev-add doesn't know about the device that the backend will be attached to, this is a legacy -drive concept. Move the remaining checks that use it to drive_init(). [Fam Zheng <famz@redhat.com> suggested line-wrapping to 80 chars as required by the coding standard. I have fixed this. --Stefan] Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
