Subject: [PATCH 3/3] checkpatch: use proper way for show problematic line

From: Thorsten Leemhuis <linux@...mhuis.info>

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.

Both problems were found by Joe Perches.
