[Crash-utility] [PATCH] Fix for swap used percentage reporting when totalswap_pages is 0.

[John Siddle]

Without the patch, when totalswap_pages is 0, swap used percentage
reports as 100%. This is confusing on first glance as it seems to
indicate potential memory pressure. Fix this and also fix indentation on
'pct' calculations to improve readability.
