iommu: arm-smmu: place print_ctx_regs properly

print_ctx_regs() is getting called after doing the ecats operations and
thus some debug info registers like fsr, fsynr will get override and
thus represents the ecats transaction rather than the real client
transaction. As an example, say faulty transaction from real client is
write but the ecats operation is always going to be read and accordingly
fsr updates.
