worktree: delete dead code

This "link" was a feature in early iterations of multiple worktree
functionality for some reason it was dropped [1]. Since nobody creates
this "link", there's no need to check it.

This is mostly used to let the user moves a worktree manually [2]. If
you move a worktree within the same file system, this hard link count
lets us know the worktree is still there even if we don't know where it
is.

We support 'worktree move' now and don't need this anymore.
