commit eee4287febb296afae3de9e21c5d9cbae14a9802

    rand: Add missing check for rand_get_global
    
    As the potential failure of the rand_get_global(),
    for example fail to get lock, 'dgbl' could be NULL
    pointer and be dereferenced later.
    Therefore, it should be better to check it and return
    error if fails, like RAND_get0_primary() and other callers.
