[qca-nss-clients] bridgemgr changes to update STP state with special WAN interface

In case if an interface is marked as special WAN interface for
a bridge device, change STP state to FORWARDING when this special
interface leaves bridge. Otherwise it leaves STP state of interface
leaving br-lan into disabled state and results into drop at PPE.
