039a40aa3b SecurityPkg: Variable drivers robustly handle crashes during Reclaim().
PEI variable implementation checks only the variable header signature for validity. This does not seem robust if system crash occurred during previous Reclaim() operation. If the crash occurred while FTW was rewriting the variable FV, the signature could be valid even though the rest of the FV isn't valid.
Solution: PEI variable and early phase(before FTW protocol ready) of DXE variable can check the FTW last write status provided by FaultTolerantWritePei and determine if all or partial variable data has been backed up in spare block, and then use the backed up data.
