Be a little more forgiving of lame BIOS writers.  If a link device that
doesn't have any actual interrupts is listed in a _PRT entry, only print
a warning rather than panic'ing when we walk the _PRT's to build up count
of entries that reference a given link (the counts are used as weights so
that we can attempt to balance the load across IRQs used by link devices).
Instead, only panic if we attempt to use the _PRT entry to route an
interrupt for a device.
