[CIFS] cifs: clarify the meaning of tcpStatus == CifsGood
When the TCP_Server_Info is first allocated and connected, tcpStatus == CifsGood means that the NEGOTIATE_PROTOCOL request has completed and the socket is ready for other calls. cifs_reconnect however sets tcpStatus to CifsGood as soon as the socket is reconnected and the optional RFC1001 session setup is done. We have no clear way to tell the difference between these two states, and we need to know this in order to know whether we can send an echo or not. Resolve this by adding a new statusEnum value -- CifsNeedNegotiate. When the socket has been connected but has not yet had a NEGOTIATE_PROTOCOL request done, set it to this value. Once the NEGOTIATE is done, cifs_negotiate_protocol will set tcpStatus to CifsGood. This also fixes and cleans the logic in cifs_reconnect and cifs_reconnect_tcon. The old code checked for specific states when what it really wants to know is whether the state has actually changed from CifsNeedReconnect.
