Btrfs-progs: add a dummy backref if our location is wrong

Browse source 
If our location is bogus in our dir item we were just skipping the thing.
However in this case we want to just delete the dir index, so create a dummy
inode rec using BTRFS_MULTIPLE_OBJECTIDS and just add every backref we find to
the list so we know to straight up delete all of these items.  Thanks,
