For the AP+AP SCC LTE-Coex case, when channel avoidance event
is reported, the channel switch request for SAP will be blocked
by policy manager if the target channel is different with the
operating channel of the existing SAP due to the SCC policy.
Need to update the logic to give higher priority to the channel
avoidance request.
Another change is to move the dfs_radar_found ref counter from
hdd_ctx to hdd_adapter so that the channel switch request of
the 2nd SAP will not be blocked when the 1st one is still in
progress since it might take some time to get VDEV restart
response from FW.

When gApAutoChannelSelection is set to 1 in ini, HOST driver ACS
runs in wlan_hdd_cfg80211_start_bss() with all the channel width,
hw mode and start and end channel parameters overridden with the
values from ini. After scan on all the channels, a weight is
assigned to all the channels based on rssi and no. of BSS present
on that channel. Weights of all the channels not present in the
scan list remains 0 as no scan happened on those channels and so
BSS count is 0 and RSSI is max. As the channel with lowest weight
is selected, channel which is not even present in scan list is getting
selected.
Assign SAP_ACS_WEIGHT_MAX to all the channels not in the scan list so
only one of the channel present in scan list gets selected after ACS
algorithm is completed.

In the api sap_get_channel_list, list is allocated memory to store the
channel list to be sent for scan request. This api is called by
sap_goto_channel_sel which initializes scan_request.ChannelInfo.ChannelList
to channel_list, without any prior NULL check of channel_list.
Also in scan callback wlansap_scan_callback, if the state machine structure
is in disconnected state , the host returns without freeing the memory
allocated to the channel list in sap_ctx .
Fix is to free the memory allocated to the channel list
and make the sap_ctx->channellist, sap_ctx->num_of_channel
as NULL and zero respectively in both the instances.
