drm/i915: Flatten intel_dp_check_mst_status() a bit
Make intel_dp_check_mst_status() somewhat legible by humans. Note that the return value of drm_dp_mst_hpd_irq() is always either 0 or -ENOMEM, and we never did anything with the latter so we can just ignore the whole thing. We can also get rid of the direct drm_dp_mst_topology_mgr_set_mst(false) call since returning -EINVAL causes the caller to do the very same call for us.
