Markus reported that there's a weird behavior on perf top --hierarch
regarding the column length. Looking at the code, I found a debious
code which affects the symtoms. When --hierarchy option is used, the
last column length might be inaccurate since it skips to update the
length on leaf entries. I cannot remember why it did and looks like a
leftover from previous version during the development. Anyway updating
the column length often is not harmful. So let's move the code out.
