Routine Description:

  The implementation Efi Decompress GetInfo().

Arguments:

  Source      - The source buffer containing the compressed data.
  SrcSize     - The size of source buffer
  DstSize     - The size of destination buffer.
  ScratchSize - The size of scratch buffer.

Returns:

  EFI_SUCCESS           - The size of destination buffer and the size of scratch buffer are successfully retrieved.
  EFI_INVALID_PARAMETER - The source data is corrupted
