The intention seems to be to warn once when we don't wait enough for the
reset to complete. Let's use the right retry counter to accomplish that
semantic.

Thanks applied.
I will let it sit in our tree for some days as I want to see if we actually
hit the WARN_ON now. So if there is an rc8 this will be part of the next
merge window, otherwise this will somewhat come later.
