devlink: Move health reporter recovery abort logic to a separate function

Extract the health reporter recovery abort logic into a separate
function devlink_health_recover_abort().
The function encapsulates the conditions for aborting recovery:
- When auto-recovery is disabled
- When previous error wasn't recovered
- When within the grace period after last recovery
