[FIX] l10n_fr_pos_cert: add usererror for non-unalterable accounting

The error will occur when a user try to print POS inalterability check report
for pos orders when accounting is not unalterable for that company.
steps to produce:

1. install l10n_fr_pos_cert the  module
2. switch to company other than FR company
3. pos > reporting > POS inalterability check .

when the company's country is not in unalterable country :
https://github.com/odoo/odoo/blob/3b88958f5a07edf86d2fc9c8080ee46d16b872ef/addons/l10n_fr/models/res_company.py#L14-L24

1. so,`_check_pos_hash_integrity()` gets Nonetype which will lead to above
traceback, when trying to update the data dictionary.
2. Also, `_check_hash_pos_integrity()` is not defined in our standard code so ,
this commit optimize the `_get_report_values` method.
