Subject: [PATCH 2/7] checkpatch: correctly stop scanning at the bottom of a hunk

We are allowing context scanning checks to apply against the first line
of context outside at the end of the hunk.  This can lead to false
matches to patch names leading to various perl warnings.  Correctly stop
at the bottom of the hunk.
