Subject: [PATCH] di: need wait pre-link stop when process I frame [1/1]

PD#SWPL-148072

Problem:
When prelink mode, I frame may be bypassed some frames.
But under v4l decode flow, I frame can not be bypassed. Otherwise,
it will display garbage.

Solution:
When prelink mode and v4l decode case, I process flow will wait for
prelink stop and not bypass.

Verify:
Verified on txhd2
