Subject: [PATCH] [FIX] base: set vat number field as readonly on children
 partners; as it is a commercial field, it should always have the value
 defined on the parent partner.

(this is a manual forward port from https://github.com/odoo/odoo/commit/98b1fffd4e99cc8ad2862c56fbd727979c38c48b , as a new view is defined in 11.0, needing this correction too)
