v4l2_m2m_buf_done is called in lat work queue, v4l2_ctrl_request_complete
is called in core queue. The request status of output queue will be set to
MEDIA_REQUEST_STATE_COMPLETE when v4l2_m2m_buf_done is called, leading to
output queue request complete fail. Must move v4l2_ctrl_request_complete
in front of v4l2_m2m_buf_done.
Patch 1 setting request complete before buffer done
Patch 2 change flush decode from capture to output when stream off
Patch 3 flush decoder before remove all source buffer
Patch 4 using input information to get vb2 buffer
Patch 5 store source vb2 buffer
Patch 6 replace v4l2_m2m_next_src_buf with v4l2_m2m_src_buf_remove
Patch 7 remove media request checking

- add patch 5/6/7 to fix decode again issue
- add fluster test result with mt8195 platform(same with no changed):

2.18.0
The request status of output queue is set to MEDIA_REQUEST_STATE_COMPLETE
when user space dequeue output buffer. Will get below warning if the
driver calling v4l2_ctrl_request_complete to set media request complete,
must to change the function order, calling v4l2_ctrl_request_complete
before v4l2_m2m_buf_done.

queue will stop to work. If lat or core work queue in working when
remove all source buffer, will lead to remove source buffer again

vb2 buffer may be removed from ready list when lat try to get
