[dpdk-dev] [PATCH] net/bnxt: fix max ring count calculation

[Somnath Kotur <somnath.kotur@broadcom.com>]

Max Rx Ring count could be < Max stat contexts. While accounting
for stat contexts, this should be also considered and
the max ring count adjusted accordingly.

Fixes: f03e66cb64ce ("net/bnxt: limit queue count for NS3/Stingray devices")
