The actual bug was introduced already in commit aa44b2f3ecd4 ("ath11k: start vdev if a bss peer is already created"). ath11k_peer_create() was failing because for AP mode the peer is created already earlier op_add_interface() and we should skip creation here, but the check for modes was wrong. Fixing that makes AP mode work again. This shouldn't affect IPQ8074 nor QCN9074 as they have hw_params.vdev_start_delay disabled.
