mesa: use locked version of HashWalk for xfb objects

>From Chapter 5 'Shared Objects and Multiple Contexts' of
the OpenGL 4.5 spec:

   "Objects which contain references to other objects include
   framebuffer, program pipeline, query, transform feedback,
   and vertex array objects.   Such objects are called container
   objects and are not shared"
