capture-ivc: Fix race condition to update callback
Added synchronization while update, and unregister the callback for
each channel-id.
In multi-session scenario, it is observed that RCE freed channel id,
and for new session allocate same channel-id again by RCE, but capture
driver did not unregister the callback and it returns channel context
is busy and it ends up with crash.
To fix this issue, added semaphore lock for each channel-id with 2
seconds timeout.
