Michel Lespinasse 411378c37f BACKPORT: mmap locking API: add mmap_assert_locked() and mmap_assert_write_locked() 
Add new APIs to assert that mmap_sem is held.

Using this instead of rwsem_is_locked and lockdep_assert_held[_write]
makes the assertions more tolerant of future changes to the lock type.
