Hello,

I have uploaded mdadm 4.4-11+deb13u1 for proposal to trixie

[ Reason ]
As reported on #1115497, there is a memory leak in the mdmonitor daemon.
After a few weeks of operation, this can eat a few gigabytes. This is a
regression over oldstable.

[ Impact ]
Administrators of servers using mdmonitor have to restart the service
from times to times to drop the memory consumption.

[ Tests ]
This is commited upstream, and confirmed on the three servers where I
noticed the issue.

[ Risks ]
The code is a mere added unref, and commited upstream.

[ Checklist ]
  [X] *all* changes are documented in the d/changelog
  [X] I reviewed all changes and I approve them
  [X] attach debdiff against the package in (old)stable
  [X] the issue is verified as fixed in unstable

[ Changes ]
This adds an unref call corresponding to the udev_monitor_receive_device
call whose returned pointer is not stored.
