[libvirt] [PATCH] qemu: Properly reset non-p2p migration

[Jiri Denemark]

While peer-to-peer migration enters the Confirm phase even if the
Perform phase fails, the client which initiated a non-p2p migration will
never call virDomainMigrateConfirm* API if the Perform phase failed.
Thus we need to explicitly reset migration before reporting a failure
from the Perform phase API.
