zed: update zed.d/statechange-slot_off.sh
Browse files Browse the repository at this point in the history
The statechange-slot_off.sh zedlet which was added in openzfs#15200
needed to be installed so it's included by the packages.

Additional testing has also shown that multiple retries are
often needed for the script to operate reliably.
