s390/mm: Allocate page table with PAGE_SIZE granularity

Make vmem_pte_alloc() consistent by always allocating page table of
PAGE_SIZE granularity, regardless of whether page_table_alloc() (with
slab) or memblock_alloc() is used. This ensures page table can be fully
freed when the corresponding page table entries are removed.
