mlxsw: spectrum_switchdev: Add error path in mlxsw_sp_port_mc_disabled_set()

The above mentioned function just returns an error in case that
mlxsw_sp_bridge_ports_flood_table_set() fails. That means that the previous
configurations are not cleaned.

Fix it by adding error path to clean the configurations in case of error.
