[PATCH 21.11] net/cnxk: fix configuring large Rx/Tx queues

[Hanumanth Pothula]

[upstream commit 5a0f64d84bf939aba37527d511fde45e1a9f6f9e]

While configuring NIX, local variables 'nb_rxq' and 'nb_txq'
are declared as 8bit variables, leading to an integer overflow
when an application sends Rxq/Txq value greater than 255.

Hence, declare local variables, 'nb_rxq' and 'nb_txq' as 16bit
variable.

Fixes: b75e0aca84b0 ("net/cnxk: add device configuration operation")
