[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. Signed-off-by: Robert Olsson <robert.olsson@its.uu.se> Signed-off-by: David S.
