Normally, bufs[i] stores the mbuf pointer, the index of buf[i]
is the loop count i, but if header.len > buf_size, DPDK will
free the mbuf, but the loop count i still increases, so some
of the items in bufs[] might be NULL ponter, causing a potential
DPDK core. Using num_rx as the index for bufs[] solves the problem.
