[patch net] mlxsw: spectrum: Disable MAC learning for ovs port

[Jiri Pirko]

From: Yuval Mintz <yuv...@mellanox.com>

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")
