cache-tree: clean up cache_tree_update()
Make the method safer by allocating a cache_tree member for the given
index_state if it is not already present. This is preferrable to a
BUG() statement or returning with an error because future callers will
want to populate an empty cache-tree using this method.
Callers can also remove their conditional allocations of cache_tree.
Also drop local variables that can be found directly from the 'istate'
parameter.
