Getting kicked during initial connect makes you unable to join any servers until the game is restarted

[sapphyrus]

Please describe your issue in as much detail as possible:

If you get kicked in CBaseServer::ConnectClient while connecting to a server your client's reservation cookie isn't reset to 0, which makes you unable to join any non-lan servers until you either restart your game or cause your reservation cookie to reset in another way. From what I can tell the fix is simply to clear the reservation cookie in CBaseClientState::Disconnect.

Steps for reproducing this issue:

1. Connect to a community server that is either full, password protected or in lan-only mode (sv_lan 1 or no GSLT set). You will get disconnected during the initial connection.
2. Try to connect to a non-lan server where none of the connections above apply. You will get kicked for "You may only connect to this server from a lobby." (#Valve_Reject_Connect_From_Lobby).
3. Fully join a local or lan server, this sets your reservation cookie to 0.
4. Try connecting to the same server again, this time the connection will succeed.
