checkpatch: update to version 0.24

This update brings a large number of small fixes to existing checks.
Of note:

 - fixes up a number of false type detections,
 - code indent checks handle macros and continuation,
 - complex macro detection handles square bracket nesting correctly, and
 - better comment handling for case.

Complete changelog below.
