In fact, DataOffset, FilePosition and FinishedSeeking are initialized
and then used if (ReadFileInfo->Flags == READ_FILE_SEEK_AND_READ).
DoFreeAed will be set to TRUE when Data is allocated and returned from
GetAedAdsData(), and Data will be freed if (DoFreeAed) when exiting.
Use same method at 5afa5b815936e2b45a375b6521764195bed68680 to fix
the build failure.
