Breno Leitao 1f6b527baf ethtool: remove ETHTOOL_GRXRINGS fallback through get_rxnfc 
All drivers that need to report the RX ring count now implement the
get_rx_ring_count callback directly. Remove the legacy fallback path
that obtained this information by calling get_rxnfc with ETHTOOL_GRXRINGS.

This simplifies the code and makes get_rx_ring_count the only way
to retrieve the RX ring count.

Note: ethtool_get_rx_ring_count() returns int to allow returning
-EOPNOTSUPP, while the callback returns u32. The implicit conversion
is safe since RX ring counts will not exceed INT_MAX while we are still
alive.
