====================
net: convert drivers to .get_rx_ring_count()

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 the following
drivers with the new ethtool API for querying RX ring parameters.
  * hns3
  * hns
  * qede
  * niu
  * funeth
  * enic
  * hinic
  * octeontx2

PS: all of these change were compile-tested only.
