The initial statistics update runs before the PF VSI has obtained its
firmware-assigned statistics counter index. Discard that provisional
VSI baseline so the first update after initialization records the
correct hardware counter.
Without this reset, subtracting a larger provisional value from a newly
selected counter can be mistaken for a 32-bit wrap and report nearly
UINT32_MAX receive drops immediately after boot.
