Currently we perform both short IRQ handling for DP, and connector reprobing in the HPD IRQ handler. However since we need to grab connection_mutex in order to reprobe a connector, in theory we could accidentally block ourselves from handling any short IRQs until after a modeset completes if a connector hotplug happens to occur in parallel with a modeset. I haven't seen this actually happen yet, but since we're cleaning up nouveau's hotplug handling code anyway and we already have a hpd worker, we can simply fix this by only relying on the HPD worker to actually reprobe connectors when we receive a HPD IRQ. We also add a mask to nouveau_drm to keep track of which connectors are waiting to be reprobed in response to an HPD IRQ.
