Revert force-setting SysNAND when launching TWL Mode

Browse Source 
This being said, neither legacy FIRM nor DSiWare actually support
EmuNAND; installing the same TWL title on both SysNAND and EmuNAND and
then launch it from EmuNAND will work though.

It is only when exiting AGB firm that we want to boot SysNAND no matter
what, because the save file has been written on a partition in SysNAND.

This is mainly to ensure we reboot to the proper NAND in case we reboot.
