udf: Set i_generation field
Currently UDF doesn't initialize i_generation in any way and thus NFS can easily get reallocated inodes from stale file handles. Luckily UDF already has a unique object identifier associated with each inode - i_unique. Use that for initialization of i_generation. Signed-off-by: Jan Kara <jack@suse.cz>
