Check that the block-group that is found matches the objectid and offset of the free-space-info. Without this the check only verifies that there is some block-group that exists with objectid >= free-space-info's objectid. To reiterate what I mentioned in the cover letter this will cause all filesystems created with mkfs.btrfs to print this warning.
