[PATCH net-next 4/9] net: mana: convert to use .get_rx_ring_count

[Breno Leitao]

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 mana_get_rxnfc(),
remove the function entirely.
