Zhen Lei 59d9bd7274 iommu/arm-smmu-v3: Properly handle the return value of arm_smmu_cmdq_build_cmd()
1. Build command CMD_SYNC cannot fail. So the return value can be ignored.
2. The arm_smmu_cmdq_build_cmd() almost never fails, the addition of
   "unlikely()" can optimize the instruction pipeline.
3. Check the return value in arm_smmu_cmdq_batch_add().
