igb_uio: handle no IRQ fallback
Fix a couple of issues with my earlier igb_uio stuff: 1. With MSI (like MSI-X) actual IRQ number is not known until after the pci_enable_msi() is done. 2. If INTX fails, fall back to running without IRQ. This allows usermode PCI to recover and run without out IRQ for cases where PCI INTX support is broken (aka VMWare).
