  \brief sme_QosInternalModifyReq() - The SME QoS internal function to request 
  for modification of certain QoS params on a flow running on a particular AC. 
  If the request involves admission control on the requested AC, HDD needs to 
  provide the necessary Traffic Specification (TSPEC) parameters & SME might
  start the renegotiation process through ADDTS.
  
  \param pMac - Pointer to the global MAC parameter structure.
  \param pQoSInfo - Pointer to sme_QosWmmTspecInfo which contains the WMM TSPEC
                    related info as defined above, provided by HDD
  \param QosFlowID - Identification per flow running on each AC generated by 
                      SME.
