[PATCH BlueZ v2] zsh: drop no more arguments message

[Ronan Pigott <ronan@rjp.ie>]

This usage of the _message as a completion function is invalid, and
will result in an error if invoked by _arguments when the user has a
format style set for completion messages.

We can just drop this message, since it is not necessary.

Before:
  $ zstyle ':completion:*:messages' format '%d'
  $ bluetoothctl connect <TAB>
  _message:zformat:42: invalid argument: -J

After:
  $ zstyle ':completion:*:messages' format '%d'
  $ bluetoothctl connect <TAB>
  31:41:59:26:53:59  -- Bose QuietComfort 35
  11:22:33:44:55:66  -- Pixel 5
---

Included an example of the erroneous output and style setting
