net: gve: convert to use .get_rx_ring_count

Browse Source 
Convert the Google Virtual Ethernet (GVE) driver to use the new
.get_rx_ring_count ethtool operation instead of handling
ETHTOOL_GRXRINGS in .get_rxnfc. This simplifies the code by moving the
ring count query to a dedicated callback.

The new callback provides the same functionality in a more direct way,
following the ongoing ethtool API modernization.
