[Intel-gfx] [PATCH] drm/i915/selftests: Always initialise err

smatch does not track initialised values as well as gcc, and this triggers many warnings by smatch not presented by gcc. Silence smatch by initialising the error values to -ENODEV, which we use to denote internal errors. (If we see a selftest fail with a silent -ENODEV, we know smatch was right!)
