media: cx18: fix incorrect input counting

Counting the number of video and audio inputs was wrong if the
number of inputs equalled CX18_CARD_MAX_VIDEO_INPUTS or
CX18_CARD_MAX_AUDIO_INPUTS. This was a copy-and-paste from the
ivtv driver. That driver has been fixed quite a long time ago,
but we missed that this driver had the same bug.
