Subject: [PATCH net-next 1/9] net: benet: convert to use .get_rx_ring_count

Use the newly introduced .get_rx_ring_count ethtool ops callback instead
of handling ETHTOOL_GRXRINGS directly in .get_rxnfc().

Since ETHTOOL_GRXRINGS was the only command handled by be_get_rxnfc(),
remove the function entirely.
