[PATCH 21/22] arm: mm: drop ctor call for kernel page tables

Thanks to recent changes:

* pagetable_pte_ctor() does nothing for kernel page tables.

* efi_mm is also treated like a kernel mm by the page table logic,
  including ctors.

We can therefore drop the ctor call when allocating special kernel
page tables in mmu.c.
