PCI: make duplicate devfn allocation fatal
Only two callers of pci_create_simple/pci_register_device bothered to check the return value. Other cases were prone to crashing with spurious NULL pointer dereferences. Make QEMU exit with an error message when devfn is attempted to be duplicated, also applies to case when the bus is full. Remove checks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
