virtio: unify config_changed handling
Replace duplicated code in all transports with a single wrapper in
virtio.c.
The only functional change is in virtio_mmio.c: if a buggy device sends
us an interrupt before driver is set, we previously returned IRQ_NONE,
now we return IRQ_HANDLED.
As this must not happen in practice, this does not look like a big deal.

virtio-pci: do not oops on config change if driver not loaded.
for the original motivation behind the driver check.
