zed: fix typo in variable ZED_POWER_OFF_ENCLO*US*RE_SLOT_ON_FAULT

[mfoliveira]

Motivation and Context

There's a typo in the name of the variable to enable a zedlet.

Fixes 11fbcac
("zed: Add zedlet to power off slot when drive is faulted")

Description

Replace ENCLO_US_RE with ENCLO_SU_RE in the name of the variable.

Mechanical change:

$ sed -i 's/ZED_POWER_OFF_ENCLOUSRE_SLOT_ON_FAULT/ZED_POWER_OFF_ENCLOSURE_SLOT_ON_FAULT/g' cmd/zed/zed.d/zed.rc cmd/zed/zed.d/statechange-slot_off.sh

Note this changes the user-visible string in zed.rc, thus might break current users with the wrong string, but it's ~2 months since zfs-2.2.0 tag is out, thus should not be widespread yet.

How Has This Been Tested?

Before:

   $ grep -r ZED_POWER_OFF_ENCLOUSRE_SLOT_ON_FAULT
    cmd/zed/zed.d/zed.rc:#ZED_POWER_OFF_ENCLOUSRE_SLOT_ON_FAULT=1
    cmd/zed/zed.d/statechange-slot_off.sh:# ZED_POWER_OFF_ENCLOUSRE_SLOT_ON_FAULT is set in zed.rc, and the disk gets
    cmd/zed/zed.d/statechange-slot_off.sh:#   2: ZED_POWER_OFF_ENCLOUSRE_SLOT_ON_FAULT disabled
    cmd/zed/zed.d/statechange-slot_off.sh:if [ "${ZED_POWER_OFF_ENCLOUSRE_SLOT_ON_FAULT}" != "1" ] ; then

After:

    $ grep -r ZED_POWER_OFF_ENCLOUSRE_SLOT_ON_FAULT
    $

Good catch!

Thanks for the quick review, Brian and Tony!

Just a note on the failing checks: the errors are unrelated to this change (which is reasonable, since the modified config option is commented out by default, anyway).
