    NFS: Fix generic revert to snapshot flow

    While reverting to a snapshot with generic flow, we create a
    temporary volume from snapshot and copy data from temporary to the
    original volume.
    While creating this temporary volume, the snapshot is in 'restoring'
    state whereas the remotefs driver only accepts 'available' and
    'backing-up' states for this operation.
    This patch adds the 'restoring' state to the list of acceptable states.
