wifi: ath12k: fix inconsistent arvif state in vdev_create error paths

ath12k_mac_vdev_create() has three error path issues that leave arvif in an inconsistent state:

  1. When ath12k_wmi_vdev_create() fails, the function returns directly without clearing arvif->ar, which was already set before the WMI call. Subsequent code checking arvif->ar to determine vdev readiness will see a non-NULL value despite no vdev existing in firmware.

  2. When ath12k_wmi_send_peer_delete_cmd() fails in err_peer_del, the code jumped to err: skipping the DP peer cleanup and vdev rollback, leaving num_created_vdevs, vdev maps and arvif list membership live.

  3. When ath12k_wait_for_peer_delete_done() fails, the code jumped to err_vdev_del: skipping the DP peer cleanup.

Fix by changing the ath12k_wmi_vdev_create() failure to goto err instead of returning directly, routing both err_peer_del failure paths through err_dp_peer_del: for proper DP peer and vdev rollback, and consolidating the arvif state cleanup at err:.
