drm/mst: Fix NULL pointer dereference at drm_dp_add_payload_part2

[Why] Commit:

commit 54d217406afe (\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().
