driver core: don't fail attaching the device if it cannot be bound
Don't fail bus_attach_device() if the device cannot be bound.
If dev->driver has been specified, reset it to NULL if device_bind_driver()
failed and add the device as an unbound device. As a result,
bus_attach_device() now cannot fail, and we can remove some checking from
device_add().
Also remove an unneeded check in bus_rescan_devices_helper().
