  sheep: disable async ledger update for VID recycling mode

The async ledger update can cause data loss because the process of
decrementing reference count can be delayed and the target VID can be
used for newly created VDIs. This commit forbids the async update if
the cluster is formatted with VID recycling mode.

Fixes https://github.com/sheepdog/sheepdog/issues/315
