ohci1394: cleanup the "Unexpected PCI resource length" warning.

This warning happens in practice because the resource length reported by
the chipset is too large. This is not actually a problem, so don't warn
about it. If it happens to be too small, warn about that, but with
a different message so people who are used to ignoring the old message
don't.
