Fixed crash when L4D server went into hibernation mode after having had an active bot and a reserved name was used by this bot

- When going into hibernation, ClientSettingsChanged is called for remaining bots
- Hook checks bot's name against reserved names in admins config and tries to kick using IClient::Disconnect
- Method of getting IClient relies on client having an INetChannel pointer
- Bots do not have an INetChannel pointer so this results in a crash
