Mount module doesn't permit reusing `none` as mount point

SUMMARY

Ansible expects the mount point specified by path to be unique, but it's valid for multiple entries to have a mount point of none on MacOS. This is used to stop volumes from automatically mounting.

STEPS TO REPRODUCE

The following task will only create an fstab entry for the second item in the loop.

---
- name: Stop drives from mounting automatically
  hosts: all

  tasks:
  - name: Update fstab entries
    become: yes
    mount:
      src: "{{ item.src }}"
      state: present
      path: "{{ item.path }}"
      fstype: apfs
      opts: rw,noauto
    loop:
      - { src: UUID=53DCE501-F280-42C5-A579-2804CB08FDAD, path: none }
      - { src: UUID=52D02FBE-632B-4EB5-8FAD-EEB9264269B8, path: none }
