[virtio] [PATCH v2 6/6] notifications: update notifications terminology for devices

[Halil Pasic <pasic@linux.ibm.com>]

The specifications of some virtio device types are still using the old
terminology for used buffer notifications and configuration change
notifications calling these interrupts.

Let us fix that.
