Subject: [RFC PATCH] iwlwifi: yoyo: don't print failure if debug firmware is missing

Missing this firmware is not fatal, my wifi card still works. Even more,
I couldn't find any documentation what it is or where to get it. So, I
don't think the users should be notified if it is missing. If you browse
the net, you see the message is present is in quite some logs. Better
remove it.

This is only build tested because I wanted to get your opinions first. I
couldn't find any explanation about yoyo, so I am entering unknown
territory here.
