Not sure it works, but should.

And btw, this kind of command can't return a error message saying that the gamemode hasn't been found

if(strcmp(cmd, "/setmode", true) == 0) 
{
    if(IsPlayerConnected(playerid))
    {
        tmp = strtok(cmdtext,idx);
        if(!strlen(tmp))
        {
            SendClientMessage(playerid,COLOR_WHITE,"   USAGE: /setmode [gamemode name]");
            return 1;
        }
        new string[128]; // Remove this if you already have it defined
        format(string,sizeof(string),"changemode %s",tmp);
        SendRconCommand(string);
    }
    return 1;
}
