"Non-stored fields like product.template.location_id/warehouse_id cannot
be searched" log error is generated because the non-storable fields are
not searchable, so it shows a log error for those fields.

This commit added the blank filter_domain in the above fields to avoid
the log error in search.

This fix is for the "product.product" search view for the "product.template"
search view has already been fixed in https://github.com/odoo/odoo/commit/a5835a160ea3f7aea37644ed4e1a49e2e4a6effd
