Calvin noted nothing of the sort, and you know it (because I'm assuming you read the entire paragraph you posted.)
Calvin clearly states faith is the vessel that God employs to bestow grace upon the elect.
"...in what way do men receive that salvation which is offered to them by the hand of God? The answer is, by faith; and hence he concludes that nothing connected with it is our own."
God could have said He'd draw a Valentine on our foreheads in red ink or write our names under every third rock or turn all the saved sheep day-glow green so that we'd know we were saved.
But He didn't. We know we are saved because we have faith, given to us by God alone.
Calvin says 'if we bring nothing but the faith' and that 'we must look at God and at man'
Calvin is saying in this commentary that faith is from man, not from God.
You might not like what he is saying, but he is saying it.
That ok, you can ignore it like you ignore his comments on 2Pet.3:9 and Spurgeons comments on 1Tim.2:4.
