Chris Wilson 1d7a99f514 drm/i915/selftests: Create mock_engine() under struct_mutex
Calling mock_engine() calls i915_timeline_init() and that requires
struct_mutex to be held as it adds itself to the global list of
timelines. This error was introduced by commit a89d1f921c ("drm/i915:
Split i915_gem_timeline into individual timelines") but the issue was
masked in CI by the earlier lockdep spam.

Fixes: a89d1f921c ("drm/i915: Split i915_gem_timeline into individual timelines")
