Custom control mapping introduced a bug, where the filter function was
applied to every single control.
Fix it so it is only applied to the matching controls.
The following dmesg errors during probe are now fixed:
usb 1-5: Found UVC 1.00 device Integrated_Webcam_HD (0c45:670c)
usb 1-5: Failed to query (GET_CUR) UVC control 2 on unit 2: -75 (exp. 1).
