V4L/DVB (4926): Fix USBVision handling of VIDIOC_QUERYCTRL

Browse Source 
There's a better (and recommended) way for handling VIDIOC_QUERYCTRL.

This patch will fix the issue where the hardware control values were
invalid and stops the SAA7115 module from complaining about invalid values.

saa7115 4-0024: invalid brightness setting 32768
saa7115 4-0024: invalid contrast setting 49152
saa7115 4-0024: invalid hue setting 32768
saa7115 4-0024: invalid saturation setting 32768
