xlib: handle _mesa_initialize_visual()'s return value

If the call fails, we should return NULL from XMesaCreateVisual().
This was found when Waffle tried to create a visual with depth/stencil
bits = -1.  That's an illegal value for glXChooseFBConfig() and we should
return NULL in that situation.

Note: This is a candidate for the stable branches.
(cherry picked from commit 05cd6cfd5f5a128404f09c4de1a7cf12f3f6f08a)
