  when RTE_ENABLE_ASSERT is defined test_mbuf application is
failing because we are trying to attach extbuf to a cloned
buffer to which external mbuf is already attached.This patch
fixes the same.

I think we can simply remove the call to rte_pktmbuf_attach_extbuf() because
after the call to rte_pktmbuf_clone(), the mbuf is already attached.

I mean something like this:

  +++ b/app/test/test_mbuf.c
  @@ -2345,16 +2345,12 @@ test_pktmbuf_ext_shinfo_init_helper(struct rte_mempool *pktmbuf_pool)
                  GOTO_FAIL("%s: External buffer is not attached to mbuf\n",
                                  __func__);
   
  -       /* allocate one more mbuf */
  +       /* allocate one more mbuf, it is attached to the same external buffer */
          clone = rte_pktmbuf_clone(m, pktmbuf_pool);
          if (clone == NULL)
                  GOTO_FAIL("%s: mbuf clone allocation failed!\n", __func__);
          if (rte_pktmbuf_pkt_len(clone) != 0)
