Chris Wilson rightly complained that this doesn't explain the list_del
magic going on. New commit msg reads:

    To make the transition in a piece-wise and bisectable way possible,
    I've hijacked the ->owner_list from drm_sman. While transitioning, the
    list_add was done by the driver, while the list_del was still done by
    the dying sman code.
    
    Now that we are in full control of ->owner_list, do the list_del
    ourselves.

He also noted the superflous additions of INIT_LIST_HEAD and the stale
comment about spinlock locking in the idr allocation (protected by
dev->struct_mutex) that I've copied over. All fixed up and pushed out for
the moment to my fdo repo:
