mlxsw: spectrum: Disable MAC learning for ovs port

Browse Source 
[ Upstream commit fccff0862838908d21eaf956d57e09c6c189f7c5 ]

Learning is currently enabled for ports which are OVS slaves -
even though OVS doesn't need this indication.
Since we're not associating a fid with the port, HW would continuously
notify driver of learned [& aged] MACs which would be logged as errors.

Fixes: 2b94e58df58c ("mlxsw: spectrum: Allow ports to work under OVS master")
