ethtool: Fix access to uninitialized fields in set RXNFC command
The check for non-zero ring with RSS is only relevant for
ETHTOOL_SRXCLSRLINS command, in other cases the check tries to access
memory which was not initialized by the userspace tool. Only perform the
check in case of ETHTOOL_SRXCLSRLINS.
Without this patch, filter deletion (for example) could statistically
result in a false error:
# ethtool --config-ntuple eth3 delete 484
rmgr: Cannot delete RX class rule: Invalid argument
Cannot delete classification rule
Fixes: 9e43ad7a1ede ("net: ethtool: only allow set_rxnfc with rss + ring_cookie if driver opts in")
