V4L/DVB (9069): cx88: Bugfix: all client disconnects put the frontend to sleep.

Browse Source 
From the author:

"This fixes the problem where previously all client disconnects
put the analogue frontend into standby.

In the following example, the first command is succesfully
watching TV but the second command which returns EBUSY
detunes the receiver by entering it into the standby state.

tvtime -d /dev/video0 &
cat /dev/video0
"
