modesetting: Update property values at detect and uevent time
We were updating the link-status property when a uevent came in, but
we also want to update the non-desktop property, and potentially
others as well. We also want to check at detect time in case we don't
get a hotplug event.
This patch updates every property provided by the kernel, sending
changes to DIX so it can track things as well.

modesetting: Reset output_id if drmModeGetConnector failed
If drmModeGetConnector() fails in drmmode_output_detect(), we have to
reset the output_id to -1 too.
Yet another spot leading to a potential NULL dereference when handling
the mode_output member as output_id was != -1. Though, this case should
be very hard to hit.

modesetting: Use helper to fetch drmModeProperty(Blob)s
