    drm/vgem: Ditch attach trickery in the fence ioctl

    It looks like this was done purely to get a consistent place to look
    up the reservation object pointer. With the drm_prime.c helper code
    now also setting gem_object->resv for imported objects we can just use
    that pointer directly, instead of first ensuring a dma-buf exists.

    v2: Note that I screwed up the patch ordering, hence why this needed
    a Fixes: tag - CI spotted the broken intermediate state.

    Fixes: 5eab998741c8 ("drm/vgem: Drop drm_gem_prime_export")
