Subject: [PATCH 14/27] perf hists browser: Fixup the "cpu" column width calculation

From: Arnaldo Carvalho de Melo <acme@...hat.com>

Since we were not setting it to at least 3 chars ('CPU'), it was being
reset to zero when recalculating the columns width when refreshing the
screen, in 'perf top'. Fix it.
