net: thunder: convert to use .get_rx_ring_count 

Convert the Cavium Thunder NIC VF 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 removing the
switch statement and replacing it 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.
