BSU sector rebooting due to race condition between the service grant and the Constellation, Symbol Rate and FEC Adaptation (CSRF) change

A race condition between the service grant and the CSRF change causes checkpoint 94 on the WSS causing it to reboot. This problem could manifest itself when a sector successfully grants service to a specific SID and immediately after that CSRF change request comes for the CPE to which the above SID is associated with and sector tries to deny BW request for the same SID.
