qcacld-3.0: Fix issue for SMM before vdev start on 2.4ghz

Scenario:-
1. Turn on SAP and STA on 2.4ghz and 5ghz
2. Turn off SAP
3. Turn off STA
4. Turn on SAP on 2.4ghz

Issue:-
In the start ap function, the driver calls
the stop opportunistic timer and calls the handler
to goto SMM mode.
After this, the SAP checks whether it requires the
DBS or not and then requests for DBS also, but since
the driver is already in DBS mode this command gets
rejected, so there would be 2 commands in the serialization
queue which would be SMM and start AP, which would lead to
a crash as SMM is sent before a connection on 2.4ghz as
Hastings is not capable to start a vdev in 2.4ghz without
DBS mode.

Fix:-
1.Not allow SMM if the current connection requires DBS
2. Check the HW capabilty in the active command only and
not before that to protect the reliability of hw mode.
