btr: Remove btr_free_node().

This has turned out to be source for bugs. Deallocate everything
in btr_remove_node() hence making removing the node and freeing
its resources an atomic operation.

To avoid dangling pointers to freed btrn nodes, the argument of
btr_remove_node() is changed to to struct btr_node **btrnp.
