[PATCH v4 07/14] net/enetc: support ethtool ring parameters

The ethtool ring parameter query relies on the queue info ethdev
ops (.rxq_info_get/.txq_info_get) together with the descriptor
limits reported in dev_info. The PF already registered these ops,
but the VF ops tables did not, so ring parameter queries failed on
the VF.
Make enetc4_rxq_info_get() and enetc4_txq_info_get() non-static and
register them in both VF ops tables so ring parameters are reported
for both the PF and VF.
