qcacld-3.0: Update the sap channel only after sap start event
In the case of SAP restart due to a RADAR, or force SCC
due to STA vdev formed, in the SAP restart path
the driver updates the SAP channel in the global
AP context, and then sends the command to change the channel
to south bound layers to process, which may reject or accept
the command.
If the command has been accepted, the channel in the
global config would be the same as the channel configured
in the restart path, but for a case where the command was rejected
by the south bound, due to a concurrency check, or other reasons
the SAP remains on the previous channel in SCC, or MCC, with the
STA interface, but the channel in the global config is same as that
given in the restart path, so the real operating channel, and the
config channel are different.
Because of this if a fresh bringup of some vdev is to be done
according to the channel of the SAP, that would fail in some cases
( SAP on DFS channel, and STA coming, so the driver would reject MCC,
and SCC) which could be avoided if the channel of the SAP wouldnt be
configured in the restart path, and would be configured in the callback
of SAP.
Also the secondary channel of the SAP was configured as the secondary
channel configured at time of fresh SAP bringup, hence the sec channel
isn't updated after every restart of SAP.
Fix is to configure the channel of in the global AP context
only when the SAP START or CHANNEL CHANGE event comes for
the SAP. Also update the secondary channel after the CSA.
