iommu/tegra: smmu: Remove unnecessary sanity check at alloc_pdir()

alloc_pdir() is called with smmu->as[?].pdir_page == NULL. No need to check pdir_page again inside alloc_pdir(). Signed-off-by: Hiroshi DOYU <[email protected]> Acked-by: Stephen Warren <[email protected]> Signed-off-by: Joerg Roedel <[email protected]>
