media: em28xx: annotate unchecked call to media_device_register()

[ Upstream commit fd61d77a3d28444b2635f0c8b5a2ecd6a4d94026 ]

Static analyzers generate alerts for an unchecked call to
`media_device_register()`. However, in this case, the device will work
reliably without the media controller API.

Add a comment above the call to prevent future unnecessary changes.
