Subject: pci: Convert uses of pci_create() etc. with Coccinelle

Replace

    dev = pci_create(bus, type_name);
    ...
    qdev_init_nofail(dev);

by

    dev = pci_new(type_name);
    ...
    pci_realize_and_unref(dev, bus, &error_fatal);

and similarly for pci_create_multifunction().

Recent commit "qdev: New qdev_new(), qdev_realize(), etc." explains
why.

Coccinelle script:

Missing #include "qapi/error.h" added manually, whitespace changes
minimized manually, @pci_dev declarations moved manually.
