Fix Ansible warnings in Firewalld zone testing tasks

The firewalld zone verification tasks in ipaserver, ipareplica, and
ipabackup roles were triggering Ansible warnings due to variable
ipareplica_firewalld_zone not being defined when evaluating the task
name.

This fix remove the Jinja template from the task names and wrap the
tasks in a single block so the variable verification is done only once.
