WIFI-13385: Fix DFS usage during csa

[mkwacz]

We noticed two issues with DFS usage:

• can not use DFS channels with ubus channel switch command:

ubus call hostapd.wlan0 switch_chan '{"freq":5260,"bcn_count":10}' Command failed: Operation not supported

PR with fix:

• invalid opclass during channel switch with DFS channels (the same issue with hostap upstream):

"Could not convert op_class 124 channel 108 to operating frequency"

Hi,

Crated PR but not sure what is the current process with hostap patches. Should first send patch to hostap community or we can do that later?

Changes were merged and reverted from master due to build issue for 3 profiles. Fixed it and run the build: https://github.com/Telecominfraproject/wlan-ap/actions/runs/8709189657

Please review once again.
