The function media_device_new_by_entity_devname queries
media devices available in the system for containment
if given media entity. If a verification is negative
the media_device is released with media_device_unref.
In the previous approach media_device_unref was closing
all media entities it contained, which was undesirable
behavior as there might exist other initialized plugins
which had opened the same media_device and initialized
a pipeline. With this patch only the sub-devices that
belong to the pipeline of current media_device instance
will be closed.
