drm/amd/display: skip CLEAR_PAYLOAD_ID_TABLE if device mst_en is 0

Browse source

commit a1c9a1e270 upstream.

[Why]
Some dock and mst monitor don't like to receive CLEAR_PAYLOAD_ID_TABLE
when mst_en is set to 0. It doesn't make sense to do so in source
side, either.

[How]
Don't send CLEAR_PAYLOAD_ID_TABLE if mst_en is 0
