KVM: PPC: Book3S: Use correct page shift in H_STUFF_TCE

The other TCE handlers use page shift from the guest visible TCE table
(described by kvmppc_spapr_tce_iommu_table) so let's make H_STUFF_TCE
handlers do the same thing.

This should cause no behavioral change now but soon we will allow
the iommu_table::it_page_shift being different from from the emulated
table page size so this will play a role.
