[PATCH net-next 2/2] net: bcmgenet: extract GRXRINGS from .get_rxnfc

[Breno Leitao <leitao@debian.org>]

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 bcmgenet with the
new ethtool API for querying RX ring parameters.
