For MLO, vdev create request should carry ML address which will not be known during ath12k_mac_op_add_interface() as vif will be marked as ML only after links are added to it. If hw scan is requested, the vdev will be deleted post hw scan and subsequent assign_vif_chanctx call will create new vdev with ML address. But in certain cases assign_vif_chanctx could be called without any prior hw scan request and reusing the previously created vdev causes a non-ML vdev to be used for an ML vif and firmware operates the vdev in non-ML mode. Fix this by deferring vdev creation for interface until hw scan or assign_vif_chanctx request is received from mac80211.
