Set owner after restoring counters folder during warmboot (#13507) (#14435)

Why I did it
After warm reboot, show environment prints the following error:
failed to import plugin show.plugins.macsec: [Errno 13] Permission denied: '/tmp/cache/macsec'

How I did it
Set owner back to admin after restoring counters folder.

How to verify it
sudo warm-reboot, then ensure show environement does not print errors.
