Subject: [PATCH] drm/i915/selftests: Fix uninitialized variable

There is a potential execution path in which variable err is
returned without being properly initialized previously.

Fix this by initializing variable err to 0.

Addresses-Coverity-ID: 1468362 ("Uninitialized scalar variable")
Fixes: f4ecfbfc32ed ("drm/i915: Check whitelist registers across resets")
