qcacld-3.0: Send NAN disable indication to userspace upon SSR

Browse Source 
Currently, host driver sends NAN disable request to firmware and
firmware sends NAN disable indication as a response. Host driver
forwards this indication to framework. But when SSR happens,
driver needs to send this NAN disable indication to framework
as firmware lost the NAN context. This allows framework to
initiate NAN again. Send the NAN disable indication with success
status code to framework after recovery.
