    igt/gem_userptr_blits: Fix up last minute API changes

    When the patch was merged, the ioctl numbers had to be adjusted to leave
    no holes. Also there was a final piece of munging of the API to
    downgrade unsynced userptr for export over dma-buf.

Upgrade to regression since shrinker handling degrades when userspace uses too many userptr objects.
