wifi-2512 APC state gets stuck in WT mode on bootup

Browse Source 
Sometimes the APC_State mode gets stuck in WT mode
on bootup. Sometimes the APC State gets updated at
the same time as disabling the APC (SIGTERM puts it in NC mode)
So it may get updated to WT just after SIGTERM handler
puts it in NC mode.
Fix this by setting APC_State in NC mode again after disabling
the APC from opensync (wm).
