v6 -> v7:
* Patch 9:
- cleanup closed vhostfd here rather than in #14;
- add !cpr_incoming guard before saving CPR fd;
* Patch 14:
- remove closed vhostfd cleanup (moved to #9);
- lift !cpr_incoming guard before saving CPR fd - not needed with an
early return;
* Patches 15-16 (NEW):
- add qtests running cpr-transfer/cpr-exec with a vhost-vsock-pci
device attached;
- add functional test with a live guest doing host<->guest vsock
transfers across a series of CPR migrations.
