This is telling that hostapd received disassociation frame from the
client, i.e., it was the client that requested to be disconnected..

There is a short timeout on moving from disassociated state to
deauthenticated in hostapd. In other words, I would expect this to be
just cleanup on the hostapd and that was triggered by the client
deciding to disassociate.

Which client are you using? Can you get debug information from it
related to authentication and association? I would take a look at that
information to figure out why it ends up sending that disassociation
frame.
