branch: drop unused worktrees variable

Browse Source 
After b489b9d9aa (branch: use branch_checked_out() when deleting refs,
2022-06-14), we no longer look at our local "worktrees" variable, since
branch_checked_out() handles it under the hood. The compiler didn't
notice the unused variable because we call functions to initialize and
free it (so it's not totally unused, it just doesn't do anything
useful).
