DO NOT MERGE mm-video-v4l2: venc: Avoid processing ETBs/FTBs in invalid states

(per the spec) ETB/FTB should not be handled in states other than
Executing, Paused and Idle. This avoids accessing invalid buffers.
Also add a lock to protect the private-buffers from being deleted
while accessing from another thread.
