The VIDIOC_QUERYCAP function should set device_caps, but this was missing.
In addition, it set the version field as well, but that should be done by
the core, not by the driver.
If a driver doesn't set device_caps the v4l2 core will issue a WARN_ON, so
it's important that this is set correctly.

The locking scheme inside the vb2 thread is unsafe when stopping the
thread. In particular kthread_stop was called *after* internal data
structures were cleaned up instead of doing that before. In addition,
internal vb2 functions were called after threadio->stop was set to
true and vb2_internal_streamoff was called. This is also not allowed.
All this led to a variety of race conditions and kernel warnings and/or
oopses.
Fixed by moving the kthread_stop call up before the cleanup takes
place, and by checking threadio->stop before calling internal vb2
queuing operations.

Since commit da6e162d6a46 ("[media] rc-core: simplify sysfs code"), when
the IR protocol is set using the sysfs interface to the same set of
protocols that are already set, store_protocols() does not refresh the
scancode filter with the new protocol, even if it has already called the
change_protocol() callback successfully. This results in the filter
being disabled in the hardware and not re-enabled until the filter is
set again using sysfs.
Fix in store_protocols() by still re-applying the filter whenever the
change_protocol() driver callback succeeded.
The problem can be reproduced with the img-ir driver by setting a
filter, and then setting the protocol to the same protocol that is
already set:
$ echo nec > protocols
$ echo 0xffff > filter_mask
$ echo nec > protocols
After this, messages which don't match the filter were still being
received.
