Describe the bug
For some specific F1820 instance we don't print usage % properly

**Script output**
[Check 32/88] Equipment Disk Limits...                                                                            FAIL - UPGRADE FAILURE!!
  Pod  Node  Code   %   Description
  ---  ----  ----   -   -----------
  1    103   F1820  NA  Disk usage for /mnt/ifc/cfg is above normal

NA is visible instead of percentage

To Reproduce
Run a script when this kind instance of F1820 is there:

# fault.Inst
code             : F1820
ack              : no
alert            : no
annotation       : 
cause            : equipment-disk-limits-exceeded
changeSet        : avail:1959076, memAlert:minor, name:ifc:cfg, path:/mnt/ifc/cfg, used:8207252
childAction      : 
created          : 2026-02-28T17:13:04.323+00:00
delegated        : no
descr            : Disk usage for /mnt/ifc/cfg is above normal
dn               : topology/pod-1/node-107/sys/eqptcapacity/fspartition-ifc:cfg/fault-F1820
domain           : access
extMngdBy        : undefined
highestSeverity  : minor
lastTransition   : 2026-02-28T17:15:33.264+00:00
lc               : raised
modTs            : never
occur            : 1
origSeverity     : minor
prevSeverity     : minor
rn               : fault-F1820
rule             : eqptcapacity-fspartition-fs-partition-limits-exceeded-minor
severity         : minor
status           : 
subject          : high-disk-usage
title            : 
type             : operational
uid              : 
userdom          : all

The issue is with:

changeSet        : avail:1959076, memAlert:minor, name:ifc:cfg, path:/mnt/ifc/cfg, used:8207252

It this case it is different than what we see for other F1820 instances:

# fault.Inst
code             : F1820
cause            : equipment-disk-limits-exceeded
changeSet        : avail (New: 1525764), memAlert (New: minor), used (New: 9509248)

Seems like we may have different format in changeSet and script should have additional regex to parse this

Expected behavior
We should see % in the output
