qcacld-3.0: Fix connState while processing disconnect from stop adapter

If driver receive stop adapter when STA is in connecting state, driver
queue a disconnect command without changing the connState of the STA.
Now even if the disconnect is in progress the connState indicate that
the connection is in progress. This may lead to sync issues between HDD
and SME.

Fix is to set the connState to disconnecting so that HDD indicate
proper state.
