UefiCpuPkg/PiSmmCpuDxeSmm: Remove useless code in ResetTokens. 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2388

After remove Used parameter, below code in ResetTokens can also be
removed:
1. The RunningApCount parameter will be reset in GetFreeToken.
2. The ReleaseSpinLock should be called in ReleaseToken function,
   Code in this function seems like a later fix if ReleaseToken not
   Release it. We should remove code here and fix the real issue if
   existed.
