drm/amdgpu/display/mst: update mst_mgr relevant variable when long HPD
[Why & How]
Now the vc_start_slot is controlled at drm side. When we
service a long HPD, we still need to run
dm_helpers_dp_mst_write_payload_allocation_table() to update
drm mst_mgr's relevant variable. Otherwise, on the next plug-in,
payload will get assigned with a wrong start slot.
