net: hyperv: convert to use .get_rx_ring_count 

Convert the hyperv netvsc driver to use the new .get_rx_ring_count
ethtool operation instead of implementing .get_rxnfc solely for handling
ETHTOOL_GRXRINGS command. This simplifies the code by replacing the
switch statement with a direct return of the queue count.

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