iommu/arm-smmu-v3: Fix error check in arm_smmu_alloc_cd_tables
In arm_smmu_alloc_cd_tables(), the error check following the
dma_alloc_coherent() for cd_table->l2.l1tab incorrectly tests
cd_table->l2.l2ptrs.
This means an allocation failure for l1tab goes undetected, causing
the function to return 0 (success) erroneously.
Correct the check to test cd_table->l2.l1tab.
