V4L/DVB (5918): ivtv: fix TV-out VBI handling, only reset on last close.

Browse source

While decoding (MPEG or YUV) is active or when VBI output is in use, then
do not clear the VBI output of the saa7127. Only after the last user is
gone can we clear it.

This fixes the case where playback was stopped, another channel was chosen
and playback was restarted, while /dev/vbi16 was used to set the WSS
(widescreen) setting. Without this fix the WSS was reset on every stop
instead of just keeping the last value.
