Subject: checkpatch: avoid some commit message long line warnings
Fixes: and Link: lines may exceed 75 chars in the commit log.
So too can stack dump and dmesg lines and lines that seem
like filenames.
And Fixes: lines don't need to have a "commit" prefix before the
commit id.
Add exceptions for these types of lines.
