KVM: PPC: Book3S HV: Use RADIX_PTE_INDEX_SIZE in Radix MMU code
In kvmppc_unmap_free_pte() in book3s_64_mmu_radix.c, we use the
non-constant value PTE_INDEX_SIZE to clear a PTE page.
We can instead use the constant RADIX_PTE_INDEX_SIZE, because we know
this code will only be running when the Radix MMU is active.
Note that we already use RADIX_PTE_INDEX_SIZE for the allocation of
kvm_pte_cache.
