zed: prevent automatic replacement of offline vdevs

Browse Source 
When an OFFLINE device is physically removed, a spare is automatically
activated. However, this behavior differs in FreeBSD, where we do not
transition from OFFLINE state to REMOVED.
Our support team has encountered cases where customers experienced
unexpected behavior during drive replacements, with multiple spares
activating for the same VDEV due to a single disk replacement. This
patch ensures that a drive in an OFFLINE state remains in that state,
preventing it from transitioning to REMOVED and being automatically
replaced by a spare.
