drm/i915/selftests: Initialise request to silence a compiler

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