powerpc: mm: call ctor/dtor for kernel PTEs
The generic implementation of pte_{alloc_one,free}_kernel now calls the [cd]tor, without initialising the ptlock needlessly as pagetable_pte_ctor() skips it for init_mm. On powerpc, all functions related to PTE allocation are implemented by common helpers, which are passed a boolean to differentiate user from kernel pgtables. This patch aligns the powerpc implementation with the generic one by calling pagetable_pte_[cd]tor() unconditionally in those helpers.
