Jeff King 4c844c2f49 dir.c: free removed sparse-pattern hashmap entries
In add_pattern_to_hashsets(), we remove entries from the
recursive_hashmap when adding similar ones to the parent_hashmap. I
won't pretend to understand all of what's going on here, but there's an
obvious leak: whatever we removed from recursive_hashmap is not
referenced anywhere else, and is never free()d.

We can easily fix this by asking the hashmap to return a pointer to the
old entry. This makes t7002 now completely leak-free.
