    perf/qr: Use a ref-ed data to extract content

    qr_content_extract used dict_get to get the value of
    the GF_CONTENT_KEY key. dict_get does not ref the data
    before returning it so QR could be acting on freed memory
    if another thread deletes the key before then.
    This patch also fixes a race in dict_get_with_ref.

    Fix: Use dict_get_with_ref to retrieve the file contents.
