[PATCH BlueZ] zsh: use the correct completion return value

[PATCH BlueZ] zsh: use the correct completion return value

[Ronan Pigott]

The return value of a completion function is significant, if we fail to
return success additional completers may be invoked when they otherwise
should not be.

Also cleanup up the zsh completion, removing the redundant definition of
_bluetoothctl and using the _call_program helper where appropriate.
