Subject: [PATCH] scripts, checkpatch.pl, provide a better output message for commit id format errors

I put together a patch with an incorrect format and the following error
was returned by checkpatch.pl:

ERROR: Please use 12 or more chars for the git commit ID like: 'Commit
09ec54429c6d ("clocksource: Move cycle_last validation to core code")'
Commit 09ec54429c6d10f87d1f084de53ae2c1c3a81108, clocksource: Move

The message is confusing.  Change it to request that the author use the
example commit ID format.
