[11/41] mm: export dump_mm()

Commit Message

mmap_assert_write_locked() will be used in the next patch to ensure
vma write lock is taken only under mmap_lock exclusive lock. Because
mmap_assert_write_locked() uses dump_mm() and there are cases when
vma write lock is taken from inside a module, it's necessary to export
dump_mm() function.
