qcacld-3.0: Get proper channel after scan for SSID
If there is no scan cache available, csr_roam_connect
will trigger a scan and after scan complete csr will
call csr_roam_issue_connect to connect one of candidate BSS.
And driver only checks the first candidate BSS's channel
for HW mode change after scan complete.
The issue is if connect first candidate failed, the next
or other candidate BSS may require DBS in concurrency
condition and the check
policy_mgr_is_hwmode_set_for_given_chnl will be failed.
To avoid such the hw mode check failed, we need to change hw
mode early if any of BSS requires DBS mode before try to
connect the BSS candidate in list one by one.
Add API csr_scan_get_channel_for_hw_mode_change which returns
DBS required candidate channel in BSS list if available,
otherwise returns the first candidate's channel.
