Now that ZED has internal fault diagnosis and the statechange event is generated for faulted states, we can replace the io-notify and checksum-notify zedlets with one based on statechange. Reviewed-by: Tony Hutter <hutter2@llnl.gov> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Don Brady <don.brady@intel.com> Closes #5383
