Description of problem:

I ran sudo dnf offline-upgrade download (with updates-testing enabled) then sudo dnf offline-upgrade reboot in a Fedora 35 KDE Plasma installation. The update included zram-generator-1.0.1-1.fc35. On the boot after the update, I pressed Esc while the plymouth screen was shown. Errors like "Failed to start Create swap on /dev/zram0." were shown repeatedly on the screen. The journal showed errors including the following.

How reproducible:
2/2 boots

Steps to Reproduce:
1. Boot a Fedora 35 KDE Plasma installation
2. Log in to Plasma on Wayland
3. start konsole
4. update to zram-generator-1.0.1-1.fc35 which I did by
sudo dnf offline-upgrade download (with updates-testing enabled) 
sudo dnf offline-upgrade reboot
5. Reboot if needed


Actual results:
Failed to start Create swap on /dev/zram0 with zram-generator-1.0.1-1.fc35

Expected results:
swap on on /dev/zram0 would be started normally as before
