I suspect something isn't setting up the ipset rule properly in the 
first place.  Check /var/log/fail2ban.log around the time of fail2ban 
startup.

Also, are you sure you're using a firewalld action?  What does 
'fail2ban-client get postfix-sasl action' show?

Finally, Fedora 22 is EOL and you really should upgrade.
