P2P specification does not provide robust mechanism for doing this,
i.e., you may have to tear down the group and re-start it to generate a
new PSK. This would obviously be inconvenient since the other devices
would then need to join the group again.

If all the clients here are indeed P2P Clients, it should be possible to
use per-device PSK from WPS provisioning step and then revoke only the
PSK for the client that is being disconnected. While parts of this has
been implemented (WPS implementation can be configured to assign
per-device PSK), this is not fully enabled for P2P GO use at this point.
