A vmap_area can travel between different places.  For example
attached/detached to/from different rb-trees.  In order to prevent fancy
bugs, initialize a VA's list node after it is removed from the list, so it
pairs with VA's rb_node which is also initialized.

There is no functional change as a result of this patch.
