qcacld-3.0: Send De-init sequence to firmware when the modules are not enabled

Browse source 
With the new statemachine  cds start/stop will not be invoked without an
interface up from upperlayer. As part of cds stop host sends de-initialization
sequence to firmware, If there is no interface up from the upper layer and
driver gets removed, host driver dosent send the de-init
inidication to firmware and starts closing its modules because of this
fw & host are out of sync.

To migitate the issue send the de-init sequence during if the modules are
opened but not enabled.
