wifi: ath12k: handle link removal in change_vif_links() 

Currently, the link interface is deleted during channel unassignment, which
does not align with mac80211 link handling. Therefore, add changes to only
perform vdev stop during channel unassignment. The actual vdev deletion
will occur in change_vif_links().
