Description of problem:
After boot the vconsole keymap was not loaded (In DE swapped y and z are pretty obvious) and an error message appeared on the vconsole.

Version-Release number of selected component (if applicable):
systemd-udev-255.4-1-fc40.x86_64

How reproducible:
Perform a dnf system-upgrade from Fedora 39 to 40 on a virtual machine I've been upgrading for more than a decade now. The virtual machine boots to a virtual console based login rather than a graphical one.

Steps to Reproduce:
1. dnf system-upgrade download --releasever=40
2. dnf system-upgrade reboot
3. Wait for upgrade and subsequent reboot to complete

Actual results:
After a fresh boot the virtual console shows an error message:
systemd[1]: Failed to start systemd-vconsole-setup.service - Virtual Console Set
The keymap was not loaded.

Expected results:
No error message before login prompt on virtual console
Keymap loads

Google found this bug when searching for "Failed to lock /dev/console", so upstream should be aware of the problem, no reaction since mid december though: https://github.com/systemd/systemd/issues/30501
