    Fix pixel_gradient_info allocation

    In very rare cases, the work thread data needs to be re-allocated, but
    the condition in is_gradient_caching_for_hog_enabled() is not true.
    Thus, this results in no pixel_gradient_info data allocated for work
    threads and the memory write violation happens. This change fixes this
    issue.
