net: dsa: remove "ds" and "port" from struct dsa_switchdev_event_work
By construction, the struct net_device *dev passed to
dsa_slave_switchdev_event_work() via struct dsa_switchdev_event_work
is always a DSA slave device.
Therefore, it is redundant to pass struct dsa_switch and int port
information in the deferred work structure. This can be retrieved at all
times from the provided struct net_device via dsa_slave_to_port().
For the same reason, we can drop the dsa_is_user_port() check in
dsa_fdb_offload_notify().
