Fix reconnect to not defer smb3 session reconnect long after socket reconnect
Azure server blocks clients that open a socket and don't do anything on it. In our reconnect scenarios, we can reconnect the tcp session and detect the socket is available but we defer the negprot and SMB3 session setup and tree connect reconnection until the next i/o is requested, but this looks suspicous to some servers who expect SMB3 negprog and session setup soon after a socket is created. In the echo thread, reconnect SMB3 sessions and tree connections that are disconnected. A later patch will replay persistent (and resilient) handle opens.
