eth: lan966x: don't clear unsupported stats

Browse Source 
Commit 12c2d0a5b8e2 ("net: lan966x: add ethtool configuration and statistics")
added support for various standard stats. We should not clear the stats
which are not collected by the device. Core code uses a special
initializer to detect when device does not report given stat.
