checkpatch: reduce git commit description style false positives

Some lines in a commit log appear to be commit SHA1 ids like:

  ERROR: Please use git commit description style 'commit <12+ chars of sha1> ("<title line>")' - ie: 'commit 0123456789ab ("commit description")'

Reduce the false positives.
