e_comp_object: flush tbm_queue of client when client buffer is locked

if tbm_queue of client use double buffer, client can render with only
next buffer because previous buffer is locked for render update lock
and client deos not have idle buffer.

for prevening client can not render frame, send flush event to
tbm_queue of client.
