Some semaphores are not cleared on S3 boot path. For example,
mSmmMpSyncData->CpuData[CpuIndex].Present. It may still keeps the value set at
SMM runtime during S3 resume. It may causes BSP have the wrong judgement on SMM
AP's present state.
We have one related fix at e78a2a49ee. But that is
not completed.
This fix is to clear Busy/Run/Present semaphores in InitializeMpSyncData().
