test: l2fwd: lockless output queues in sched mode
Application didn't request lockless (MT_UNSAFE) output queues in scheduler mode, even when the pktio had enough queues (one tx queue per worker). Updated tx side queue configuration code to utilize lockless queues also in sched mode. Also updated queue binding print out, so that it's easy to check which queues workers are using (only tx in sched mode).

test: l2fwd: lookup table for sched mode
Replaced linear destination port search in scheduler mode with a lookup table. Table index is API provided pktio_index and data is application port index.
