spapr_iommu: drop erroneous check in h_put_tce_indirect()
The tce_list variable is not a TCE but the address to a TCE: we shouldn't
clear permission bits as we do now. And this is dead code anyway since we
check tce_list is 4K aligned a few lines above.
This patch doesn't fix any bug, it is only code cleanup.
