Wayne Lin 8e21de5f99 drm/mst: Fix NULL pointer dereference at drm_dp_add_payload_part2 
commit 5a507b7d2b upstream.

[Why]
Commit:
- commit 5aa1dfcdf0 ("drm/mst: Refactor the flow for payload allocation/removement")
accidently overwrite the commit
- commit 54d217406a ("drm: use mgr->dev in drm_dbg_kms in drm_dp_add_payload_part2")
which cause regression.

[How]
Recover the original NULL fix and remove the unnecessary input parameter 'state' for
drm_dp_add_payload_part2().

Fixes: 5aa1dfcdf0 ("drm/mst: Refactor the flow for payload allocation/removement")
