Subject: [PATCH v3 04/16] selftests/resctrl: Make "bandwidth" consistent in comments & prints

Resctrl selftests refer to "bandwidth" currently in two other forms in
the code ("B/W" and "band width").

Use "bandwidth" consistently everywhere. While at it, fix also one
"over flow" -> "overflow" on a line that is touched by the change.
