When the ExecuteSmmCoreFromSmram() function fails, SmmIplEntry() restores the SMRAM range to EFI_MEMORY_UC. However, it saves the return value of gDS->SetMemorySpaceAttributes() in the same Status variable that gDS->contains the return value of ExecuteSmmCoreFromSmram(). Therefore, if gDS->SetMemorySpaceAttributes() succeeds, the failure of ExecuteSmmCoreFromSmram() is masked, and Bad Things Happen (TM). Introduce a temporary variable just for the return value of gDS->SetMemorySpaceAttributes().
