btrfs-progs: Record orphan data extent ref to corresponding root.
Before this patch, when a extent's data ref points to a invalid key in
fs tree, this happens if a leaf/node of fs tree is corrupted, btrfsck
can't do any repair and just exit.
In fact, such problem can be handled in fs tree repair routines, rebuild
the inode item(if missing) and add back the extent data (with some
assumption).
So this patch records such data extent refs for later fs tree recovery
routine.
TODO:
Restore orphan data extent refs into btrfs_root is not the best
method. It's best to directly restore it into inode_record, however
current extent tree and fs tree can't cooperate together, so use
btrfs_root as a temporary storage until inode_cache is built.
