This update removes an unnecessary and always-true check within the Odoo POS self-ordering module. The previous code was designed to verify if the self-ordering mode was 'qr_code', but this option is no longer valid. This change streamlines the code and improves efficiency without impacting functionality.

Description of the issue/feature this PR addresses:

Removed obsolete code checking "this.config.self_ordering_mode !== 'qr_code'". 
Since "qr_code" is not a valid value of the "self_ordering_mode" selection field.
The condition is always true.
