media: v4l2-compat-ioctl32.c: make ctrl_is_pointer work for subdevs
commit 273caa260035c03d89ad63d72d8cd3d9e5c5e3f1 upstream.
If the device is of type VFL_TYPE_SUBDEV then vdev->ioctl_ops
is NULL so the 'if (!ops->vidioc_query_ext_ctrl)' check would crash.
Add a test for !ops to the condition.
All sub-devices that have controls will use the control framework,
so they do not have an equivalent to ops->vidioc_query_ext_ctrl.
Returning false if ops is NULL is the correct thing to do here.
