Wrong values when fail2ban is restarted

Hello,

Failb2ban-exporter is broken, but still running, when mountpoint is removed (with a simple fail2ban restart for example)

2022/06/15 11:02:16 error opening socket: dial unix /var/run/fail2ban/fail2ban.sock: connect: no such file or directory
2022/06/15 11:03:16 error opening socket: dial unix /var/run/fail2ban/fail2ban.sock: connect: no such file or directory
2022/06/15 11:04:16 error opening socket: dial unix /var/run/fail2ban/fail2ban.sock: connect: no such file or directory

I guess Fail2ban prometheus should exit and be restarted with restart: always (in docker-compose)
