[Piglit] [PATCH] egl_ext_device_drm: don't fail the test if open("/dev/dri/cardX") errors

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

As pointed out by Mathias opening the card node can fail in some cases.
In boils down to a) the node is owned by root:video b) by default, the
user is not part of the video group c) logind dynamically allows any
user to open the node, once a user has logged-in.

Thus if we use a remote machine accessible only over ssh, the test will
fail. A fairly common setup that one could use for their CI.

Demote the failure to a warning.
