btrfs: remove pointless label and goto at btrfs_record_unlink_dir()

There's no point of having a label and goto at btrfs_record_unlink_dir()
because the function is trivial and can just return early if we are not
in a rename context. So remove the label and goto and instead return
early if we are not in a rename.
