function commerce_option_field_attach_submit in Commerce Product Option 7.2

Implements hook_field_attach_submit().

This hook gets called in field_attach_submit(), which is called by commerce_cart_add_to_cart_form_submit(). It is here we need to add the option set property on the commerce_line_item entity. We do it here because here we have access to $form_state, which holds the values for the option set.
