hi!
currently a series of 'pci_bus_to_hose() failed' messages are printed when pciinfo() is called with a invalid (out-of-bounds) bus number.
this patch fixes the output of the 'pci' command by *) checking that the given bus number is actually a number *) checking that the given bus number is not out-of-bounds before doing a scan *) printing 'pci_bus_to_hose() failed' only when DEBUG is defined
