Commitde85488138("drm/panthor: Add the scheduler logical block") handled destruction of a group's queues' drm scheduler entities early into the group destruction procedure. However, that races with the group submit ioctl, because by the time entities are destroyed (through the group destroy ioctl), the submission procedure might've already obtained a group handle, and therefore the ability to push jobs into entities. This is met with a DRM error message within the drm scheduler core as a situation that should never occur. Fix by deferring drm scheduler entity destruction to queue release time.
