Memory allocation for h_t and c_t #12

I think it would be a tiny bit faster if you allocate the whole memory for h_t and c_t from the beginning in OptimizedLSTM. I mean:

    if init_states is None:
        h_t, c_t = (torch.zeros(bs, self.hidden_size).to(x.device),
                    torch.zeros(bs, self.hidden_size).to(x.device))

instead of:

    if init_states is None:
        h_t, c_t = (torch.zeros(self.hidden_size).to(x.device),
                    torch.zeros(self.hidden_size).to(x.device))
