Fixing following issues:

Editing config values in Qocm_cfg.ini disables "save settings" option on GUI.

After fastboot, when SoftAP turned ON first time beacon shows WMM and Country elements info but SoftAP UI shows these options as disabled

After selecting the save-settings button GUI was always sending the command to change the energy_detect_threshold. Code is updated to send
it only if energy_detect_threshold is changed

Bug fixed to return correct security mode

Error happened after saving the SoftAP configuration
