net: dsa: make the STP state function return void
The DSA layer doesn't care about the return code of the port_stp_update
routine, so make it void in the layer and the DSA drivers.
Replace the useless dsa_slave_stp_update function with a
dsa_slave_stp_state function used to reply to the switchdev
SWITCHDEV_ATTR_ID_PORT_STP_STATE attribute.
In the meantime, rename port_stp_update to port_stp_state_set to
explicit the state change.
