[media] ivtv: avoid going past input/audio array
As reported by smatch:
drivers/media/pci/ivtv/ivtv-driver.c:832 ivtv_init_struct2() error: buffer overflow 'itv->card->video_inputs' 6 <= 6
That happens because nof_inputs and nof_audio_inputs can be initialized
as IVTV_CARD_MAX_VIDEO_INPUTS, instead of IVTV_CARD_MAX_VIDEO_INPUTS - 1.
