Bug#1035094: udev: /dev/serial/by-id/ symlinks not created anymore for USB devices

[Felix Geyer]

Package: udev
Version: 247.3-7+deb11u2
Tags: bullseye

Since udev 247.3-7+deb11u2 /dev/serial/by-id/* symlinks are not created anymore for USB serial
devices.
This is a regression from backporting udev-always-create-device-symlinks-for-USB-disks.patch

It was fixed upstream by https://github.com/systemd/systemd/pull/25246

The diff doesn't apply cleanly because we don't have
https://github.com/systemd/systemd-stable/commit/451ba55fecd8b494add2001b3ca3c1915c8fd655

Apply this commit and the PR fixes the issue for me.

I think it's the same root cause, but I also noticed that the
ID_SERIAL_SHORT attribute has disappeared from `udevadm info` for USB
serial adapters. ID_USB_SERIAL_SHORT is present, but ID_SERIAL_SHORT
is gone, which has broken some udev rules which use ID_SERIAL_SHORT
for matching.

I was affected by the same bug after a Bullseye update to version 11.7:
no more /dev/serial/by-id/* symlinks.

I confirm that the fix in https://github.com/systemd/systemd/pull/25246
solved the issue.
