mlx4: extract GRXRINGS from .get_rxnfc
Commit 84eaf4359c36 ("net: ethtool: add get_rx_ring_count callback to
optimize RX ring queries") added specific support for GRXRINGS callback,
simplifying .get_rxnfc.
Remove the handling of GRXRINGS in .get_rxnfc() by moving it to the new
.get_rx_ring_count().
This simplifies the RX ring count retrieval and aligns mlx4 with the new
ethtool API for querying RX ring parameters. This is compiled tested
only.
