[PATCH] app/test-crypto-perf: fix invalid mbuf next operation

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.
