The command "ethtool -L <intf> combined 0" may clean the RX/TX channel
count and skip the error path, since the attrs
tb[ETHTOOL_A_CHANNELS_RX_COUNT] and tb[ETHTOOL_A_CHANNELS_TX_COUNT]
are NULL in this case when recent ethtool is used.
Tested using ethtool v5.10.
Fixes: 7be92514b9 ("ethtool: check if there is at least one channel for TX/RX in the core")
