REF: https://bugzilla.tianocore.org/show_bug.cgi?id=704 For root directory, the FID (File Identifier Descriptor) pointer is accessible through PRIVATE_UDF_FILE_DATA.Root, whereas non-root directory and regular files, their FIDs are accessible through PRIVATE_UDF_FILE_DATA.File. In UdfSetPosition(), the FID was retrieved through PRIVATE_UDF_FILE_DATA.File, hence when calling it with a root directory, PRIVATE_UDF_FILE_DATA.File.FileIdentifierDescriptor would be NULL and then dereferenced. This patch fixes the NULL pointer dereference by calling _FILE() to transparently return the correct UDF_FILE_INFO * which points to a valid FID descriptor of a specific file.
