glx: Make __glXGetDrawableAttribute return true sometimes

Browse source 
Right now it always returns zero, but as of:

        glx: Prepare driFetchDrawable for no-config contexts

We were hoping it would return true if the drawable could actually be
looked up. It wasn't, so that didn't go very well. With the most recent
update to <GL/glxext.h> glXQueryGLXPbufferSGIX (correctly) returns void,
so there's no longer anything else besides driFetchDrawable that depends
on the return value from __glXGetDrawableAttribute.
