If an instance having iSCSI volumes attached is being
live-migrated, a Planned VM is created at the destination.
If the live-migration fails, the Planned VM is not cleaned
up at the destination.
This patch will ensure that rollback_live_migration_at_destination
is being called on live-migration failure for Hyper-V compute nodes,
which will clean up the Planned VM.
