qcacld-3.0: Issue LFR2.0 connect only in proper CSR state

Browse Source 
In DBS, LFR 2.0 takes more time to complete the roaming sequence
due to DBS config changes through policy manager. If roaming is
in progress and cfg80211 issues disconnect, disconnect handler is
supposed to wait for 4 sec before processing. In some DBS scenarios,
4 sec wait timer can expire and disconnect proceed for clean up
before the roaming sequence can complete, results in race condition.
Thus adding CSR state check before proceeding with LFR issue connect.
