[VGAMP/VGADDI] Be consistent in IOCTL_VIDEO_GET_CURRENT_MODE and IOCTL_VIDEO_SET_CURRENT_MODE

As IOCTL_VIDEO_GET_CURRENT_MODE returns 2 as ModeIndex, wait for the same value
    in IOCTL_VIDEO_SET_CURRENT_MODE.
    Also change vgaddi to send this hardcoded value.

vga_new also uses 2 as index for 640x480x16
