[2.3.0] Checkmk Werk 16899 created: oracle_locks: allow checking w/o setting a state

[//]: # (werk v2) # oracle_locks: allow checking w/o setting a state key | value ---------- | --- compatible | yes version | 2.3.0p20 date | 2024-10-22T13:48:29+00:00 level | 1 class | feature component | checks edition | cre Setting levels for oracle_locks to (0, 0) or not setting any levels at all makes the check plugin either compare with 0 or with default levels, making it impossible to avoid WARN or CRIT results without fully disabling the check. This change skips checking against levels if both warn and crit levels have been set to 0, thus keeping the behavior for default levels.
