The current UNKNOWN_COMMIT_ID doesn't check for 41+ length commit id,
and although GIT_COMMIT_ID will check for 41+ length commit id, but
it willn't warn anything about it due to 41+ length commit will never
be defined.
This patch moves the unknown commit id check for normal commit description
to GIT_COMMIT_ID, and uses ERROR instead of WARN, because unknown commit
id is total useless to track change history in changelog, it deserves the
ERROR.

After this patch, in another patch 'checkpatch: add support to check 'Fixes:' tag format',
I will delete UNKNOWN_COMMIT_ID, because we don't need it anymore after GIT_COMMIT_ID could
do the same check as UNKNOWN_COMMIT_ID for 'Fixes:' tag.
