[media] dvb_frontend: pass the props cache to get_frontend() as arg
Instead of using the DTV properties cache directly, pass the get frontend data as an argument. For now, everything should remain the same, but the next patch will prevent get_frontend to affect the global cache. This is needed because several drivers don't care enough to only change the properties if locked. Due to that, calling G_PROPERTY before locking on those drivers will make them to never lock. Ok, those drivers are crap and should never be merged like that, but the core should not rely that the drivers would be doing the right thing.
