Could we copy the kmod-openafs only depending on the module for the latest kernel over from 6.4 to the other repos?

I'm afraid I made a mistake when leaving the kabi dependencies in the modules without testing all these cases again. I think next time we touch the package, those deps should simply go.

Sorry for the problem,
