Subject: arm: __pmd_free_tlb(): call page table desctructor
As long as PMD tables are accounted as PTE tables ("mm: account PMD tables
like PTE tables") they can be freed only after pgtable_pmd_page_dtor() is
called.
Add the missing call in ARM's version of __pmd_free_tlb for
CONFIG_ARM_LPAE=y case.
