[compute] always set instance.host in post_livemigration
This change add a new _post_live_migration_update_host
function that wraps _post_live_migration and just ensures
that if we exit due to an exception instance.host is set
to the destination host.
when we are in _post_live_migration the guest has already
started running on the destination host and we cannot revert.
Sometimes admins or users will hard reboot the instance expecting
that to fix everything when the vm enters the error state after
the failed migrations. Previously this would end up recreating the
instance on the source node leading to possible data corruption if
the instance used shared storage.
