media: v4l: subdev: Set sd->devnode before registering the subdev
The subdev's video device node was only assigned after registering the
device node in the system. While it is unlikely that a driver needed to
use this field in handling system calls to its file handle, there remains
a slim chance the devnode field remains NULL while the driver expects to
find a video node there.
Assign the devnode field before registering the device, and assign it back
to NULL if the registration failed.
