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 <hdoyu@nvidia.com> Acked-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
