qcacld-3.0: Address race between ap stop and system suspend

A race between cfg80211 ap stop and wiphy system suspend can lead
to either DPM WD or serialization VDEV disconnect active command
timeout since scheduler thread gets suspended as part of wiphy
suspend and both cfg80211_disconnect and wiphy suspend/resume acquire
RTNL lock.
To address this race condition avoid ap stop when wiphy
suspend is already completed since scheduler thread gets suspended
as part of wiphy suspend and it can't process ap stop.
