[PATCH] scripts: fix commit check of first word

[Thomas Monjalon <thomas.monjalon@6wind.com>]

The first word of each commit message is checked.
But when the commit range was greater than 1, only the latest commit
was checked.
It is fixed by checking each commit separately.

Fixes: 9c24780f0d5e ("scripts: check first word of commit messages")
