V4L/DVB (10820): meye: Don't need to zero ioctl parameter fields
The v4l2 core code in v4l2_ioctl will zero out the structure the driver is
supposed to fill in for read-only ioctls. For read/write ioctls, all the
fields which aren't supplied from userspace will be zeroed out.
Zeroing code is removed from querycap, enum_input, enum_fmt_vid_cap, and
g_fmt_vid_cap.
