ccd: add distinct return code to indicate that password is required
When user is trying to execute 'ccd open' or 'ccd unlock' and password
is set, the return error code does not allow to tell the reason for
the command failure.
Let's add a distinct return code to indicate this condition so that
the user can supply password.
BRANCH=cr50
BUG=b:62537474
TEST=verified along with the accompanying gsctool modifications.
