Subject: checkpatch: use proper way for show problematic line

Instead of using an unnecessarily complicated approach to print a line
that is warned about, use `$herecurr` instead, just like everywhere else
in checkpatch.

While at it, remove a superfluous space in one of the changed lines, too. 
In a unmodified line also remove a superfluous check for a space before a
signed-off-by tag, to me consistent with the check at the start of the
section.

All three problems were found by Joe Perches during review of new code
inspired by the code modified here.
