mm/mmap: change detached vma locking scheme
Don't set the lock to the mm lock so that the detached VMA tree does not
complain about being unlocked when the mmap_lock is dropped prior to
freeing the tree.
Introduce mt_on_stack() for setting the external lock to NULL only when
LOCKDEP is used.
Move the destroying of the detached tree outside the mmap lock all
together.
