DVDInterface: Fix decrypting reads clearing the drive state

This broke ejecting Wii discs while the game is running, as the drive state was set to Ready even when no disc was present, but other code still reported the missing disc, which confused games as you can't be both ready to read and have no disc.  That would cause games to show an unrecoverable error screen, instead of a "please insert the game disc" screen.

This only affected Wii games; the GameCube games used regular disc reads which worked fine.
