The Starling-X collectd alarm notification handler Fault Manager (FM)
call to clear an alarm can lead to a stuck alarm if that FM request
fails, say due to a concurrent swact operation, and the clear is not
retried.
The alarm will remain stuck until there is another same alarm assertion,
followed by deassertion that leads to a successful clear.
The fix is to execute a 'return' in the alarm clear failure path so
that the alarm notifier's alarm manager control structure is not
updated with the clear state so that the clear will be automatically
retried on the next audit interval.
