    em: remove M_HASHTYPE when RSS is not enabled
    
    Summary:
    Since "73fe85e486d2 tcp: store flowid info in syncache", inp_flowid can be set
    if the incoming packet is not M_HASHTYPE_NONE. But this can introduce dummy
    and duplicated flowid when a virtual interface set M_HASHTYPE_OPAQUE. This
    change will let the upper layer know how to deal with software hash, with
    benefits like inp_flowid can be set correctly and m_pkthdr.flowid can be set
    correctly in output path.
    
    This fix is similar to "20285cad7a55"
