Allow mismatched virtio config-len
Commit 'virtio: validate config_len on load' restricted config_len
loaded from the wire to match the config_len that the device had.
Unfortunately, there are cases where this isn't true, the one
we found it on was the wce addition in virtio-blk.
Allow mismatched config-lengths:
*) If the version on the wire is shorter then fine
*) If the version on the wire is longer, load what we have space
for and skip the rest.
(This is mst@redhat.com's rework of what I originally posted)
