mm: replace mmap with vma write lock assertions when operating on a vma

Browse source

Vma write lock assertion always includes mmap write lock assertion and
additional vma lock checks when per-VMA locks are enabled. Replace
weaker mmap_assert_write_locked() assertions with stronger
vma_assert_write_locked() ones when we are operating on a vma which
is expected to be locked.
