powerpc/iommu: Avoid derefence before pointer check [ Upstream commit 984ecdd68de0fa1f63ce205d6c19ef5a7bc67b40 ] The tbl pointer is being derefenced by IOMMU_PAGE_SIZE prior the check if it is not NULL. Just moving the dereference code to after the check, where there will be guarantee that 'tbl' will not be NULL.
