drm/display/dp_mst: Fix drm_dp_mst_add_affected_dsc_crtcs() return code
Looks like that we're accidentally dropping a pretty important return code
here. For some reason, we just return -EINVAL if we fail to get the MST
topology state. This is wrong: error codes are important and should never
be squashed without being handled, which here seems to have the potential
to cause a deadlock.
