checkpatch: suppress errors triggered by short patch 



When the last hunk of a patch is short it will trigger errors from
checkpatch:

    Use of uninitialized value in pattern match (m//)
	    at /usr/local/bin/checkpatch.pl line 394.
    Use of uninitialized value in concatenation (.) or string
	    at /usr/local/bin/checkpatch.pl line 397.
    Use of uninitialized value in pattern match (m//)

Avoid touching beyond the last line.  Reported by Julien Brunel.
