[PATCH] Xdmx: Initialize DMX extension even if not built with GLX support

[Alan Coopersmith]

dmxAddExtensions takes an argument to determine if it should just
initialize the DMX extension, or both DMX & GLX, but if GLX wasn't
compiled in, the entire call was #ifdef'ed out, leaving the DMX
extension unavailable.
