Jeff Layton c46c887744 vfs: document locking requirements for d_move, __d_move and d_materialise_unique ...

Adding a comment to d_materialise_unique per Al's request...

d_move and __d_move have some pretty substantial locking requirements,
but they are not clearly documented. Add some comments spelling them
out. Also, document the requirement for the i_mutex of the parent in
d_materialise_unique.
