In fill_multi_seg_mbuf(), when remaining_segments is 0,
rte_mbuf m's next should pointer to NULL instead of a
new rte_mbuf, that casues setting m->next as NULL out
of the while loop to the invalid mbuf.

This commit fixes the invalid mbuf next operation.

Fixes: bf9d6702eca9 ("app/crypto-perf: use single mempool")

Hi Suanming,

Good catch. Please see inline.

[Anoob] Would it make sense to move assignment of next_mbuf also to here? That way, the checks will become self explanatory.
  		next_mbuf = (struct rte_mbuf *) ((uint8_t *) m +

Make sense. Maybe just like that:
  		m->next = (struct rte_mbuf *) ((uint8_t *) m +
  					mbuf_hdr_size + segment_sz);
		m = m->next;

What do you think?

[Anoob] Yes. That's even better. 

I think we can have line lengths upto 100 characters now. In case you find it easier to put in single line.

In fill_multi_seg_mbuf(), when remaining_segments is 0,
rte_mbuf m's next should pointer to NULL instead of a
new rte_mbuf, that causes setting m->next as NULL out
of the while loop to the invalid mbuf.

This commit fixes the invalid mbuf next operation.

Fixes: bf9d6702eca9 ("app/crypto-perf: use single mempool")

v2: move next_mbuf inside remaining_segments check.
