[FlexiDag] BlockStorage::delete_block don't processe dag_sync_block_storage

#[derive(Clone)]
pub struct BlockStorage {
    block_store: BlockInnerStorage,

    pub fn delete_block(&self, block_id: HashValue) -> Result<()> {
        self.header_store.remove(block_id)?;
        self.body_store.remove(block_id)?;
        self.block_store.remove(block_id)?;
        self.block_txns_store.remove(block_id)?;

    }

if we need self.dag_sync_block_storage.remove(block_id)
