Subject: [PATCH v2 19/20] drm/dp_mst: Drop DRM_ERROR() on kzalloc() fail in drm_dp_mst_handle_up_req()

Checkpatch was complaining about this - there's no need for us to print
errors when kzalloc() fails, as kzalloc() will already WARN for us. So,
let's fix that before converting things to make checkpatch happy.
