blacklist.conf: commit 9def3b1a07c4 not needed
    
    Mainline commit 9def3b1a07c4 ("iommu/vt-d: Don't dereference iommu_device
    if IOMMU_API is not built") is a build fix which is only needed for config
    with CONFIG_IOMMU_API disabled. As both SLE15-SP2 and openSUSE-15.2 have
    CONFIG_IOMMU_API=y in all configs where applicable, we don't need this
    build fix.
