net/bonding: fix packet count type for LACP

net/bonding: fix packet count type for LACP

Caught by code review, those variables are supposed to be on 16bits to
avoid endless loops in the (unlikely?) case where the application asks
for receiving more than 256 packets and the accumulated num_rx_total
count reaches 256:

uint16_t num_rx_total = 0;
uint8_t j, k;

j = num_rx_total;
num_rx_total += rte_eth_rx_burst();

for (k = j; k < 2 && k < num_rx_total; k++)
	rte_prefetch0(rte_pktmbuf_mtod(bufs[k], void *));

while (j < num_rx_total) {
	j++;
}
