To the best of my knowledge firmware does not support frame injection
on monitor vdev. Therefore this is expected. Moreover this limitation
is mentioned on ath10k wiki:

You could probably hack up the driver to create and use AP or STA vdev
alongside monitor vdev to use it's vdev_id for frame injection. I'm
not aware of anyone trying that out so far though.
