When we construct the boundary mesh we build elements coincident with the
boundary directly from the interior elements.  At that time the boundary
element's 'parent' is set to the interior element it came from.

So you should be safe iterating over the elements in the boundary mesh and
querying their parent - that should return the element from the original
mesh with no searching.
