There is a case that ExtractGuidedSectionGetInfo return 0 for ScratchBufferSize and ScratchBuffer will be NULL, after AllocatePool fails to allocate buffer for AllocatedOutputBuffer, the code will call FreePool (ScratchBuffer), but ScratchBuffer == NULL. This patch is to only free ScratchBuffer when it is not NULL.
