This function allows to remove all media entity's links to other entities, leaving no references to a media entity's links array at its remote entities. Currently, when a driver of some entity is removed it will free its media entities links[] array, leaving dangling pointers at other entities that are part of same media graph. This is troublesome when drivers of a media device entities are in separate kernel modules, removing only some modules will leave others in an incorrect state. This function is intended to be used when an entity is being unregistered from a media device. With an assumption that normally the media links should be created between media entities registered to a media device, with the graph mutex held.
