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.
