function countries_country_field_validate in Countries 7

We need to transform the field values here to complete the requirements for the field custom handling of multiple values.

This converts the array('AU' => 'AU', 'US' => 'US') to array(0 => array('iso2' => 'AU'), 1 => array('iso2' => 'US')).

See also

countries_country_element_validate() for validation.
