[FIX] fleet: Fix access error on assign driver linked to internal user

Currently, Failing at base/models/res_partner.py#L535
We write on the partner because of the related `plan_to_change_car`

When Assign driver linked to internal user without admin rights
it gives an error in security rules due to write on partner.

So while creating the vehicle when driver is assigned pop the value
for related field plan_to_change_car and rewrite the same with sudo.

closes odoo/odoo#60358
