The only iommu function call in this driver is a
tegra_dev_iommu_get_stream_id() which does not allocate anything and does
not take any reference.
More-over, what is freed is "se->dev" which has been devm_kzalloc()'ed in
the probe.
So there is no point in calling iommu_fwspec_free() in the remove function.
Remove this incorrect function call.
