If the nb_pkts parameter to rte_eth_tx_burst() was greater than
the TX descriptor count, a completion was not being requested
from the NIC, so descriptors would not be released back to the
host causing a lock-up.
Introduce a limit of how many TX descriptors can be used in a single
call to the enic PMD burst TX function before requesting a completion.
