Bug fix: Only reset a failed state if present to avoid error

[andanotheruser]

Description

Fixes an issue where a failed state is reset while none is present, leading to an error and the playbook failing:

  TASK [ansible-mariadb-galera-cluster : manage_node_state | reset failed status (otherwise service can't be stopped)] ***
  fatal: [node2]: FAILED! => {"changed": false, "cmd": ["systemctl", "reset-failed", "mariadb"], "delta": "0:00:00.007486", "end": "2024-11-14 11:43:51.597408", "msg": "non-zero return code", "rc": 1, "start": "2024-11-14 11:43:51.589922", "stderr": "Failed to reset failed state of unit mariadb.service: Unit mariadb.service not loaded.", "stderr_lines": ["Failed to reset failed state of unit mariadb.service: Unit mariadb.service not loaded."], "stdout": "", "stdout_lines": []}
  skipping: [node1]

This change ensures a failed state is only reset if it is present and will fix the merge request pipeline for #227, #229 and #230

Not yet sure why this fails on Rocky.

Found it.

mariadb_systemd_service_name must include the full name. Ansible will fail with mariadb on some distributions, as it does not have the key in the dict: ansible_facts.services[mariadb_systemd_service_name].state, however, using the full unit name solves this.

@eRadical This MR will fix an issue that causes the pipeline of my other two MRs to fail. :)
