st/mesa: Fix recurring surfaceless contexts
A current incomplete framebuffer was incorrectly used as a st_framebuffer. When accessing st_framebuffer childs bad things happen: e.g. st_framebuffer::iface was used to check whether its an incomplete fb, instead we need to compare st_framebuffer::Base against mesa_get_incomplete_framebuffer. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=44919 Note: This is a candidate for the 8.0 branch. Reviewed-by: Brian Paul <[email protected]>
