We need to be careful in case other devices grow an error file in the
future. The first step here is just to check the minor that corresponds

As /sys/class/drm/cardX/error is a new interface for 3.11, we need to be
quiet when it does not exist or else we upset the automated tests.

In preparation to have sysfs entries used in scripts
rename to more specific name.
