wifi patches

When no wifi module is connected to the system, all nn::ac::Connect calls will fail, since /dev/net/ifmgr/ncl cannot be opened without /dev/net/ifmgr/wd being opened successfully. This is done to ensure that the wifi driver (wifi24) has finished successfully, which will of course never happen without a wifi module.
This causes some funny issues in /dev/emd, since it will abort and go into an endless loop causing the console to freeze due to the cooperative thread model in IOS. This patch simply allows opening /dev/net/ifmgr/ncl without /dev/net/ifmgr/wd, maybe don't use this on a console with an actual wifi module installed though.
