Fix crash in virtio_blk during modprobe ; rmmod ; modprobe
Fix a modprobe virtio_blk ; rmmod virtio_blk ; modprobe virtio_blk crash; this was basically because we weren't doing "del_gendisk()" in the remove path. Signed-off-by: Chris Lalancette <clalance@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (moved del_gendisk up)
