qcacld-3.0: cleanup NAN state upon NAN enable/disable timeout

Browse Source 
Currently, driver sends NAN enable/disable request to firmware
and waits for the response. NAN state is cleaned up when NAN
disable indication is received. But if firmware doesn't respond to
NAN enable or disable request, a timeout happens and NAN state is
not cleaned up.
Cleanup the NAN state upon timeout for NAN enable/disable request.
