__tbm_queue_sequence_enqueue: enqueue only one the surface

__tbm_queue_sequence_enqueue: enqueue only one the surface

For example you dequeued the surfaces 1, 2.
If you enqueue the surface 2 the enqueue operation will be failed but
the priv_flags will remain 0. Then when you enqueue the surface 1 the
enqueue operation will be successful but you have enqueued the surface 2
too because the priv_flags for the surface 2 is 0. But you got the error
for the enqueue operation of surface 2. And you can try again to enqueue
the surface 2. But you will get the
TBM_SURFACE_QUEUE_ERROR_ALREADY_EXIST
error.
So I think we need enqueue only one the surface if it is first in the
dequeue_list
