dix: remove unused and half-broken code to restore original classes.

Browse source 
In theory, the MD should change back to its old, original classes when the
last SD is detached. Thanks to the XTEST devices, we'll always have an SD
attached until the MD is removed.  So let's not worry about that and do
nothing instead of having some code that's essentially untested.
