qcacld-3.0: Avoid fw crash in some wow case on third party

Due to the limitation on third party platform, add ini to take
special care of the below wow case to avoid fw crash.
The sap/p2p_go shall kick out all the connected sta/p2p_gc and
then go to suspend if d0wow/d3wow is not supported.
Although there is wakelock try to prevent suspend after tdls link
setup, it won't take effect because auto sleep mechanism is not
supported on some third party platform, so teardown tdls link
by force before suspend.
