Subject: [PATCH net v2 2/4] octeon_ep: remove firmware stats fetch in ndo_get_stats64

The per queue stats are available already and are retrieved
from register reads during ndo_get_stats64. The firmware stats
fetch call that happens in ndo_get_stats64() is currently not
required

Fixes: 6a610a46bad1 ("octeon_ep: add support for ndo ops")
