[virtio] [PATCH 2/5] consistency: clean up stale wording for v1.1 terms

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

Occasionally we still use used and available ring instead of Device and
Driver Area respectively. Same goes for descriptor table with the
difference that depending on the context we need either Descriptor Area
or descriptor ring.

Let's clean these up, at least where the cleanup is trivial.
