net/bnxt: fix accumulation of flow counters

OVS-DPDK is accumulating the flow counters that are returned as part of
the flow_query API and it is being issued at least 3 times every second.
So there is no need to accumulate the counts internally in the driver.

Fixes: 306c2d28e247 ("net/bnxt: support count action in flow query")
