The result of container_of() operations is never NULL unless the embedded
element is the first element of the structure. This is not the case here.
The NULL check is therefore unnecessary and misleading. Remove it.

Before the video device node is registered, the v4l2_dev.mdev
pointer must be set in order to correctly associate the video
device with the media device. Move the initialization of the
media device up.

Prevent NULL (or close to NULL) pointer dereference in various places by
registering the video device only when the V4L2 m2m framework has been set
up.

We never use _ in directory names in the media subsystem, so
rename to test-drivers instead for consistency.
Also update MAINTAINERS with the new path.
