iommu/arm-smmu: Always set resume to terminate the transaction

When using the client fault handler, set resume to terminate the
faulting transaction similar to the way of the default fault
handler.

Its possible that if the client fault handler doesn't "fully"
handle the fault, there would be a stream of page faults on the
same address since we would keep on retrying the same
transaction.
