MSI: Remove dev->first_msi_irq
Now that we keep a list of msi descriptors, we don't need first_msi_irq in the pci dev. If we somehow have zero MSIs configured list_entry() will give us weird oopes or nice memory corruption bugs. So be paranoid. Add BUG_ONs and also a check in pci_msi_check_device() to make sure nvec > 0.
