[PATCH net-next 1/2] net: mvneta: convert to use .get_rx_ring_count

[Breno Leitao <leitao@debian.org>]

Convert the mvneta 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.
