REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2683 This patch fixes an assertion because AP can't find the CpuMpData. When AP is waken up through Init-Sipi-Sipi, AP's IDT should be restored to pre-allocated buffer so AP can get the CpuMpData through the IDT base address. Current code already has logic to handle this when CpuMpData-> InitFlag is ApInitConfig but misses the logic when CpuMpData->InitFlag is ApInitReconfig. This patch fixes this gap.
