net: mscc: ocelot: remove unnecessary variable

Commit 2f187bf ("net: ethernet: ocelot: remove the need for num_stats initializer") added a flags field to the ocelot stats structure. The same behavior can be achieved without this additional field taking up extra memory. Remove this structure element to free up RAM Suggested-by: Vladimir Oltean <[email protected]> Signed-off-by: Colin Foster <[email protected]> Reviewed-by: Vladimir Oltean <[email protected]> Tested-by: Vladimir Oltean <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>
