    [HIFN]: Have HW invalidate src and dest descriptors after processing
    
    The descriptors need to be invalidated after processing for ring
    cleanup to work properly and to avoid using an old destination
    descriptor when the src and cmd descriptors are already set up
    and the dst descriptor isn't.
