In __btrfs_free_extent we will print the leaf if we fail to find the extent we wanted, but the problem is if we get an error we won't have a leaf so often this leads to a NULL pointer dereference and we lose the error that actually occurred. So only print the leaf if ret > 0, which means we didn't find the item we were looking for but we didn't error either. This way the error is preserved.
