[PATCH] GLX: Avoid a crash if we ever end up trying to use glapi_noop_table

I'm not sure if this is patch-worthy or not, but whilst getting GLX to work
again on Cygwin/X I came across this...
If the GL dispatch table pointer points to glapi_noop_table, (due to some kind
of terrible failure during GL initialization), running glxinfo for e.g. will
crash the X server, as DoGetString(GL_VERSION) tries to do atof() on the null
pointer returned by the noop dispatch function.
Given that all that noop dispatch table stuff is in there, I guess it's
preferable that it doesn't crash in that case.
