Change em28xx_dvb_fini() to set fe exit flag to DVB_FE_DEVICE_REMOVED
when device is disconnected. em28xx maintains device disconnect status
in em28xx device. fe drivers will be able to now check the fe exit
status to avoid accessing the device, from their release interfaces
when called from disconnect path. This change depends on dvb-core
change that exports fe exit flag by moving it from fepriv to fe.

endpoints > 0
The current code assumes that the analog + digital video endpoints are always at
interface number 0 when changing the alternate setting.
This seems to work fine for most existing devices.
However, at least the SpeedLink VAD Laplace webcam has the video endpoint on
interface number 3 (which fortunately doesn't cause any trouble because ist uses
bulk transfers only).
We already consider the actual interface number for audio endpoints, so
rename the the audio_ifnum variable and use it for all device types.
Also get get rid of a pointless (ifnum < 0) in em28xx-audio.

Putting em28xx in suspend mode when a feed stops is just plain
wrong. Every time a new PES filter is changed, the DVB demux
code will stop the current feed, and then start a new one.
If are there any code that switches off the frontend, via
some GPIO setting, this would make the DVB fail.
This condition was actually trigged with one device, during
DVB scan, as, during scan, it is common that userspace apps
to change the filter several times, in order to get all
tables.
Also, this is not needed at all, since the em28xx code already
hooks into ops.ts_bus_ctrl(). This warrants that em28xx can
check there if DVB frontend is in usage or not. The code there
already puts the device on suspend mode, if the DVB frontend
is not used (closed).

The current enpoint logic ignores all bulk endpoints and uses
a fixed mapping between endpint addresses and the supported
data stream types (analog/audio/DVB):
Ep 0x82, isoc => analog
Ep 0x83, isoc => audio
Ep 0x84, isoc => DVB
Now that the code can also do bulk transfers, the endpoint
logic has to be extended to also consider bulk endpoints.
The new logic preserves backwards compatibility and reflects
the endpoint configurations we have seen so far:
Ep 0x82, isoc => analog
Ep 0x82, bulk => analog
Ep 0x83, isoc* => audio
Ep 0x84, isoc => digital
Ep 0x84, bulk => analog or digital**
(*: audio should always be isoc)
(**: analog, if ep 0x82 is isoc, otherwise digital)
