Patch that fixes the segfault

Chromium can crash Xorg when the nouveau DRI driver is loaded. This is due to a
nullpointer dereference.

Archlinux bug (Xorg crash): https://bugs.archlinux.org/task/33994
Fedora bug (Application crash, same cause):
https://bugzilla.redhat.com/show_bug.cgi?id=862466

As suggested in the Fedora bug, comment 15, attached is a patch that fixes this
issue (confirmed on Archlinux). This is the same check the Intel DRI driver
does, so I think it's needed there.
