mm: pgtable: introduce generic pagetable_dtor_free()

The pte_free(), pmd_free(), __pud_free() and __p4d_free() in
asm-generic/pgalloc.h and the generic __tlb_remove_table() are basically
the same, so let's introduce pagetable_dtor_free() to deduplicate them.

In addition, the pagetable_dtor_free() in s390 does the same thing, so
let's s390 also calls generic pagetable_dtor_free().
