client: hud: don't overwrite teamnumber in ScoreInfo

[Vladislav4KZ]

Possible fix for: #402

The original CS 1.6 client does not overwrite teamnumber in MsgFunc_ScoreInfo. See the pseudocode from the decompilation of the original Steam client.so, specifically the CounterStrikeViewport::MsgFunc_ScoreInfo function:

BEGIN_READ(pbuf, iSize);
v4 = READ_BYTE();
v5 = READ_SHORT();
v6 = READ_SHORT();
playerclass = READ_SHORT();
READ_SHORT(); // <-- the team number is read here, but it is not assigned to teamnumber
if ( (unsigned __int16)(v4 - 1) > 0x3Fu )
return 1;
v7 = v4;
v8 = g_PlayerExtraInfo[v7].teamnumber >= 0;
g_PlayerExtraInfo[v7].frags = v5;
g_PlayerExtraInfo[v7].deaths = v6;
g_PlayerExtraInfo[v7].playerclass = playerclass;
