LP#2006749: Fix call to ou_ancestor_setting_perm_check in AppUtils.pm

LP#2006749: Fix call to ou_ancestor_setting_perm_check in AppUtils.pm

The $self and $e arguments are missing when the ou_ancestor_setting
subroutine calls ou_ancestor_setting_perm_check in AppUtils.

The $coust argument also need to be $coust->view_perm->code for the
allowed check in ou_ancestor_setting_perm_check.

This commit corrects the call to ou_ancestor_setting_perm_check.
