We represent PCI intpin's two different ways.  One is the way that the
intpin register is expressed in hardware where 0 means none, 1 means INTA,
2 INTB, etc.  The other way is commonly used in loops where 0 means INTA,
1 means INTB, etc.  The matchpin argument to pci_cfgintr_search() is
supposed to be the first form, but we passsed in a loop index of the
second.  This fix adds one to the loop index to convert to the first form.
