[PATCH] drm/dp_mst: Correct the bug in drm_dp_update_payload_part1()

[Wayne Lin]

[Why]
If the payload_state is DP_PAYLOAD_DELETE_LOCAL in series, current
code doesn't delete the payload at current index and just move the
index to next one after shuffling payloads.

[How]
After shuffling payloads, decide whether to move on index or not
according to payload_state of current payload.
