In MLO scenario WCN7850 firmware requests the assoc link to associate before any other links. However currently in ath12k_mac_op_vif_cfg_changed() we are doing association in an ascending order of link id. If the assoc link does not get assigned the smallest id, a non-assoc link gets associated first and firmware crashes. Change to do association for the assoc link first.
