Btrfs: make free space caching faster with many non-inline extent references
So to cache free space, we iterate every extent item to gather free space info.
When we have say 10,000 non-inline extent refs(such as BTRFS_EXTENT_DATA_REF),
it takes quite a long time, and since inline extent refs and non-inline ones have
same objectid in their keys, we can just re-search the tree with the next address
to skip non-inline references.
(This is found by dedup feature because dedup extents can end up with many
non-inline extent refs.)
