crypto: tegra - Remove an incorrect iommu_fwspec_free() call in tegra_se_remove()

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.

So there is no point in calling iommu_fwspec_free() in the remove function.

Remove this incorrect function call.
