From: Matthew Wilcox <mawilcox@xxxxxxxxxxxxx>
Subject: radix tree test suite: handle exceptional entries
item_kill_tree() assumes that everything in the tree is a pointer to a
struct item, which is annoying when testing the behaviour of exceptional
entries. Fix it to delete exceptional entries on the assumption they
don't need to be freed.
