[media] dvb-usb: create one media_dev per adapter
Instead of assuming just one adapter, change the code to store
one media controller per adapter.
This works fine for dvb-usb, as, on all drivers here, it is not
possible to write a media graph that would mix resources between
the two different adapters.
