EEH kernel services are inconsistently exported by the

While eeh_check_failure is implemented for a specific 
purpose to be used by services such as readl, it is 
not suited for a purpose where caller needs eeh status. 
This functionality is provided by eeh_dev_check_failure.

This patch relaxes the export for eeh_dev_check_failure
to make it consistent with eeh_check_failure() and 
usable by non-GPL modules.

The GPL covers all derivative works. Tweaking this doesn't magically
allow you to use the feature in non GPL code. Your legal department can I
am sure explain in detail further.
