session: memory leak in mma rule table

When the rule table is allocated, the root node is allocated. But it
cannot be deleted by the add_del API, or the table is useless.

When the table is free, the root node is not free and there is memory
leak. Let's add pool_flush when the rule table is free.

Type: fix
