[PATCH v3 10/33] radix tree test suite: Handle exceptional entries

Matthew Wilcox

From: Matthew Wilcox <mawilcox@microsoft.com>

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.
