Revert "Ensure initrd is rebuilt when dkms module is updated ."
This reverts commit aff81712.
The wider range of DKMS modules are of questionable quality. As such the end-user should be the one explicitly opting in, to add them to their initird.
As such automatically adding/rebuilding the initrd on this trigger should not exist - revert the change.
