So if you pick the creation feat, you can substitute your cleric caster level. If you do not pick the creation feat, you do not meet (most) CL requirements and thus add 5 to your DC.

(But honestly just learn Crafter's Fortune from a scroll to boost your DC by 5.)
Further addendum:

You still cannot upgrade the item, because you do not even count as having any relevant feat yet. That's what the wizard CL is for - you need CL to get pseudo CWI from arcane bond, not for any checks.
