iommu/arm-smmu-v3: Do not continue in __arm_smmu_domain_inv_range()

The loop in the __arm_smmu_domain_inv_range() is a while loop, not a for
loop. So, using "continue" is wrong that would fail to move the needle.

Meanwhile, though the current command is skipped, the batch still has to
go through arm_smmu_invs_end_batch() to be issued accordingly.

Thus, use "break" to fix the issue.
