update checkpatch.pl to version 0.14

This version brings the remainder of the queued fixes.  A number of fixes
for items missed reported by Andrew Morton and others.  Also a handful
of new checks and fixes for false positives.  Of note:

 - new warning associated with --file to try and avoid cleanup only patches,
 - corrected handling of completly empty files,
 - corrected report handling with multiple files,
 - handling of possible types in the face of multiple declarations,
 - detection of unnessary braces on complex if statements (where present), and
 - all new comment spacing handling.
