[S390] incorrect PageTables counter for kvm page tables
The page_table_free_pgste function is used for kvm processes to free page tables that have the pgste extension. It calls pgtable_page_ctor instead of pgtable_page_dtor which increases NR_PAGETABLE instead of decreasing it. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
