Previously, this has been done implicitly for video device nodes by calling
set_input() (which calls audio_input() and also modified the mute
setting).
Since input and mute setting are now untangled (as much as possible), we need to
apply the mute setting with an explicit call to audio_mute().
Also apply the mute setting when the radio device node gets opened.

store_protocols() treats dev->rc_map.rc_type as a bitmap which is wrong for
two reasons. First of all, it is pretty bogus to change the protocol type of
the keymap just because the hardware has been asked to decode a different
protocol.
Second, dev->rc_map.rc_type is an enum (i.e. a single protocol) as pointed
out by James Hogan <james.hogan@imgtec.com>.
Fix both issues by introducing a separate enabled_protocols member to
struct rc_dev.

I just made commit: "dvb_usb_v2: rework USB streaming logic" that
breaks that driver PID filter.
it913x driver checks use of PID filter directly from DVB USB v2 core
internal variable "adap->pid_filtering" and stores it to own state.
Calling order of .pid_filter_ctrl() and .pid_filter() was changed
and due to that state was updated too late. Update state earlier.
TODO: checking PID filter usage from DVB USB v2 is not very good idea
as PID filter callbacks are called only when PID filter is enabled.

Control flow order changed a little bit. HW PID filter is now
disabled also when streaming is stopped - earlier it was just
set only when streaming was started.
Control flow is now:
* set streaming status bit
* submit USB streaming packets
* enable HW PID filter
* ask device to start streaming
* N x add PID to device HW PID filter
... streaming video ...
* N x remove PID from device HW PID filter
* ask device to stop streaming
* disable HW PID filter
* kill USB streaming packets
* clear streaming status bit
