xkb: don't overwrite CtrlProc in the second run of XkbFinishDeviceInit.

Browse Source 
XkbFinishDeviceInit is called once when the device is initialised, but also
when a class copy causes the key class of a device to change. In this case,
overwriting the CtrlProc of the KeybdFeedbackClass with XkbDDXKeybdCtrlProc
sets up a nice recursive loop of XkbDDXKeybdCtrlProc calling itself until the
cows come home.
