iommu/arm-smmu: fix incorrect comment regarding TLB invalidation
Commit 1463fe44fd0f ("iommu/arm-smmu: Don't use VMIDs for stage-1
translations") moved our TLB invalidation from context creation time to
context destruction time, but forgot to update an associated comment.
This patch fixes the broken comment.
