iommu: Fix two issues in iommu_copy_struct_from_user()
In the review for iommu_copy_struct_to_user() helper, Matt pointed out that
a NULL pointer should be rejected prior to dereferencing it:

And Alok pointed out a typo at the same time:
https://lore.kernel.org/all/480536af-6830-43ce-a327-adbd13dc3f1d@oracle.com
Since both issues were copied from iommu_copy_struct_from_user(), fix them
first in the current header.
