[media] cx18: avoid going past input/audio array
As reported by smatch:
drivers/media/pci/cx18/cx18-driver.c:807 cx18_init_struct2() error: buffer overflow 'cx->card->video_inputs' 6 <= 6
That happens because nof_inputs and nof_audio_inputs can be initialized
as CX18_CARD_MAX_VIDEO_INPUTS, instead of CX18_CARD_MAX_VIDEO_INPUTS - 1.
