virtio_blk: ioctl return value fix
Block driver ioctl methods must return ENOTTY and not -ENOIOCTLCMD if they expect the block layer to handle generic ioctls. This triggered a BLKROSET failure in xfsqa #200. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
