When OS sends more packets than are being read with a single
'rte_eth_rx_burst' call, rx packets are getting stucked in the tap pmd
and are unable to receive, because trigger_seen is getting updated
and consecutive calls are not getting any packets.
Do not update trigger_seen unless less than a max number of packets were
received allowing next call to receive the rest.
v1 to v2 changes:
- fix typo in commit description
- remove unnecessary compiler barrier
