qcacld-3.0: Optimize NAN state machine when driver recovers

Currently, host driver sends NAN enable and disable request to
firmware and wait for its response to change the NAN state in
driver. But, when firmware is down (during SSR), driver is in
recovery state and so, timeout occurs while waiting for response.

To fix this, driver does not need to wait for NAN enable/disable
response from firmware in recovery state. It can directly take the
action and change the NAN state machine. Hence, add flag to check
the driver recovery state. If recovery is in progress, then driver
does not wait for firmware NAN enable/ disable responses.
