[Intel-gfx] [PATCH] drm/i915/selftests: Fix uninitialized variable

[Gustavo A. R. Silva]

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")
