Replace the existing virtnet_get_rxnfc callback with a dedicated
virtnet_get_rxrings implementation to provide the number of RX rings
directly via the new ethtool_ops get_rx_ring_count pointer.

This simplifies the RX ring count retrieval and aligns virtio_net with
the new ethtool API for querying RX ring parameters.
