Timo Strunk 24d29008f0 fix(kms): skip empty DRM cleanup commit in display_configuration
display_configuration() issued an ALLOW_MODESET atomic commit on every udev
event, even when no planes needed detaching. The empty commit is a no-op
modeset that interferes with in-flight commits on the render thread, and it
fails with EPERM whenever we don't hold DRM master (e.g. a render-only
secondary GPU), aborting device enumeration.

Track whether any property was added and skip the commit when there is nothing
to do. A commit that does have changes still propagates its error as before, so
a genuine failure to apply cleanup is not silently swallowed.
