[PATCH] glx: Pass GLX drawable ID to DRI2CreateDrawable().

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

Otherwise the DRI2Drawable may retain references to the destroyed
__GLXDRIdrawable, leading to use after free in __glXDRIinvalidateBuffers().

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=50019
