The __mock_request_alloc() implements the smoketest->request_alloc()
function pointer. It's called from __igt_breadcrumbs_smoketest().
It's supposed to return error pointers, and returning NULL will lead to
a NULL pointer dereference.
Fixes: 52c0fdb25c7c ("drm/i915: Replace global breadcrumbs with per-context
interrupt tracking")
