Paulo Alcantara 11b4463e09 MdeModulePkg/UdfDxe: Fix NULL pointer dereference 
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.
