net: mscc: ocelot: remove unnecessary variable

Commit 2f187bfa6f35 ("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
