As Ted pointed out, it can happen that ext3_truncate() returns without removing inode from orphan list. This way we could in some rare cases (like when we get ENOMEM from an allocation in ext3_truncate called because of failed ext3_write_begin) leave the inode on orphan list and that triggers assertion failure on umount. So make ext3_truncate() always remove inode from in-memory orphan list.
