Currently, ieee80211_num_beaconing_links() returns 0 when the interface
operates in non-ML mode. However, non-MLO mode is equivalent to having a
single link. Therefore, the function can handle the non-MLO case as well.
This adjustment will also eliminate the need for deflink usage in certain
scenarios.

Hence, implement changes to handle the non-MLO case as well. There is
no change in functionality, and no existing user-visible bug is getting
fixed. This update simply makes the function generic to handle all cases.
