[0/3] ath11k: vdev and peer delete synchronization with firmware

Message

When add an interface immediately after removing the interface,
vdev deletion in firmware might not have been completed.
add vdev_delete_resp_event and wait_event_timeout to synchronize
with firmware.

Peer creation in firmware fails if last peer deletion is still in
progress, add wait for the event after deleting every peer from host
driver to synchronize with firmware.

1) add vdev delete resp event and wait event to get ack from firmware
2) add wait event timeout for peer delete to get ack from firmware
3) code clean up and replace the api 'ath11k_mac_get_ar_vdev_stop_status'
   with 'ath11k_mac_get_ar_by_vdev_id'

  ath11k: remove "ath11k_mac_get_ar_vdev_stop_status" references
