switchdev: Pass original device to port netdev driver
switchdev drivers need to know the netdev on which the switchdev op was invoked. For example, the STP state of a VLAN interface configured on top of a port can change while being member in a bridge. In this case, the underlying driver should only change the STP state of that particular VLAN and not of all the VLANs configured on the port. However, current switchdev infrastructure only passes the port netdev down to the driver. Solve that by passing the original device down to the driver as part of the required switchdev object / attribute. This doesn't entail any change in current switchdev drivers. It simply enables those supporting stacked devices to know the originating device and act accordingly.
