drm/i915/selftests: Initialise request to silence a compiler
With an old (4.7.3 on 32bit) gcc, it emits a warning for
In file included from drivers/gpu/drm/i915/i915_request.c:1425:0:

drivers/gpu/drm/i915/selftests/i915_request.c:380:21: error: ‘request’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
