bridge: mrp: Fix the usage of br_mrp_port_switchdev_set_state
The function br_mrp_port_switchdev_set_state was called both with MRP
port state and STP port state, which is an issue because they don't
match exactly.
Therefore, update the function to be used only with STP port state and
use the id SWITCHDEV_ATTR_ID_PORT_STP_STATE.
The choice of using STP over MRP is that the drivers already implement
SWITCHDEV_ATTR_ID_PORT_STP_STATE and already in SW we update the port
STP state.
Fixes: 9a9f26e8f7ea30 ("bridge: mrp: Connect MRP API with the switchdev API")
Fixes: fadd409136f0f2 ("bridge: switchdev: mrp: Implement MRP API for switchdev")
Fixes: 2f1a11ae11d222 ("bridge: mrp: Add MRP interface.")
