Fix issue: systemctl daemon-reload would sporadically cause udev handler fail (#15253) (#15959)
A workaround to back port the fix for a systemd issue.

The systemd issue: systemd/systemd#24668
The systemd PR to fix the issue: https://github.com/systemd/systemd/pull/24673/files

The formal solution should upgrade systemd to a version that contains the fix. But, systemd is a very basic service, upgrading systemd requires heavy test.
