SmiHandlerUnRegister() validates the DispatchHandle by checking whether the first 32bit matches to a certain signature (SMI_HANDLER_SIGNATURE). But if a caller calls *UnRegister() twice and the memory freed by first call still contains the signature, the second call may hang. The patch fixes this issue by locating the DispatchHandle in all SMI handlers, instead of checking the signature.
