[PATCH xserver] xephyr: Fix regeneration

[Adam Jackson]

I had said:

    commit c42311a9d7d2e5a67bdb7f4fa32032b4feba59b1
    Author: Adam Jackson <ajax at redhat.com>

        kdrive: Remove KdOsFuncs

        Only the Init slot was used, and Xephyr can just as easily do
        that initialization directly.

And I'd've been right, but I forgot to make that initialization only
happen on startup (i.e. when serverGeneration == 1).
