[dpdk-dev] [PATCH] net/ixgbevf: fix stats update after a PF reset

The stats register can rewind to zero when the port is running for a long period.
So I am afraid that this check is not always correct.
Why not introduce a variable to directly indicate whether the resulted stats
should be updated or not.
