DRM does not always update the status of each connector during a
hotplug event, and it's generally expected that userspace is supposed to
handle that by reprobing. This happens in a couple situations:
suspend/resume, MST hotplugs, and probably a few others. As a result,
making this assumption actually breaks MST hotplugging.
