Subject: [PATCH v2,0/4] media: mediatek: vcodec: fix ctrl request complete fail

Moving v4l2_ctrl_request_complete to before of function
v4l2_m2m_buf_done to make sure the status of request correctly.

Replace v4l2_m2m_next_src_buf with v4l2_m2m_src_buf_remove to
make sure the src buffer won't be removed for some unknown
reason leading to buffer done error.

Patch 1 setting request complete before buffer done
Patch 3 flush decoder before remove all source buffer
Patch 2 change flush decode from capture to output when stream off
Patch 4 replace v4l2_m2m_next_src_buf with v4l2_m2m_src_buf_remove
---
compared with v1:
- add patch 2/3/4 to fix timing issue.
