Fix type mismatch in FSFS verify_moves code, currently not inactive
on /trunk.

The problem is that changed path list arrays contain change_t *
instances while hashes contain svn_fs_path_change2_t *. Make sure
to use the correct element type depending on the container type.

* subversion/libsvn_fs_fs/transaction.c
  (check_for_duplicate_move_source): use the "smaller" type as argument
                                     since that can always be provided
  (verify_moves): use the correct element types
