[PATCH] fib_trie.c node freeing fix

Please apply to 2.6.{14,15,16} -stable, thanks a lot.

[FIB_TRIE]: Fix leaf freeing.

Seems like leaf (end-nodes) has been freed by __tnode_free_rcu and not
by __leaf_free_rcu. This fixes the problem. Only tnode_free is now
used which checks for appropriate node type. free_leaf can be removed.
