CameraHAL: Clear events queue fix, clear command queue on exit

Fix 2/3 for b/5593964.

1. The events queue wasn't being cleared correctly inside
OMXCameraAdapter as some items were being removed while the
index was being formulated based on the original size
2. The command queue should be cleared before posting the EXIT
message for the OMX adapter threads so as not to process those
messages since we are exiting
