cluster/unify: don't call xl_init_tree on namespace node.

- just before xl_init_tree call on namespace, unify node is set as parent of
    namespace node and since xl->ready of unify node is set only after return
    from init call, calling xl_init_tree on namespace node will result in
    execution of init of unify node for the second time. This results in
    following bugs:

    * since during second execution, parent of namespace node is unify, init of
      unify xlator fails.
    * even if init did not fail, re-execution of init in itself is bad, since it
      results in memory leaks etc. Worse, it can result in infinite recursive
      calls into init of unify node.
