cx88-blackbird: fix vidioc_g_tuner never ending list of tuners
From: Jelle Foks <jelle@foks.8m.com>
v4l-info and other programs would loop indefinitely while querying the
tuners for cx88-blackbird cards.
The cause was that vidioc_g_tuner didn't return an error value for
qctrl->id != 0, making the application think there is a never ending
list of tuners...
This patch adds the same index check as done in vidioc_g_tuner() in
cx88-video.
