    drivers/video: Initialize flags member of query control APIs
    
    video driver does not support flags member of ioctl(VIDIOC_QUERYCTRL)
    and ioctl(VIDIOC_QUERY_EXT_CTRL).
    But, ioctl returns with the flags member that has the garbage value.
    Add initialization of flags member to avoid return of the garbage value.
