[PATCH 2/4] drm/mst: Some style improvements in drm_dp_mst_topology_mgr_set_mst()

[Lyude Paul]

JFYI: I'm going to go ahead and push this patch by itself to drm-misc-next
since it applies cleanly, the other patches in this series don't depend on
this, and I'm about to send out a patch that modifies the code around these
hunks anyway.
