Recursively query descendant tids until we get a cover nid.

Warning! This is probably quite intensive, as it drills down the term hierarchy doing a query on each term until it finds a node -- and this is done for EVERY row of the main gallery term view!

Parameters

$tid The tid whose children we should investigate for a cover nid.:

$recurse The current recursion depth.:
