[dpdk-dev] [PATCH v3 2/3] ring: rename fields in internal data struct

[Ferruh Yigit <ferruh.yigit@intel.com>]

Rename nb_rx/tx_queues fields in internals struct to max_rx/tx_queues

This patch just does variable renaming to help understanding code better,
nothing changed in functionality of the code.

Updated fields required to keep max queue numbers configured. For current
queue number requirements data->nb_rx/tx_queues fields used.
