This patch is to fix the issue reported from https://bugzilla.tianocore.org/show_bug.cgi?id=925.
DataSize variable was not assigned the value if ShellOpenFileByName returns error. In the such a case, it should not be used to FreePages. Instead, DataSize can be used to record the file size once DownloadFile successfully.
