net/bnxt: fix stats counter resource

The flow counters is reduced from 8192 to 6912 for Whitney
for compatibility with different versions of FW.
The FW resource manager splits resources for flow offload
and other use cases. A higher value used for flow offload
by the PMD can cause overriding the resources set aside by
FW. This in turn can lead to FW rejecting filter creation
requests during initialization.

Use a smaller safe value to avoid these issues.
