ethdev: fix data type in TC queues

Currently, base and nb_queue in the tc_rxq and tc_txq information
of queue and TC mapping on both TX and RX paths are uint8_t.
However, these data will be truncated when queue number under a TC
is greater than 256. So it is necessary for base and nb_queue to
change from uint8_t to uint16_t.
