Functions called from device_setup_unit() already make sure that unit is enqueued in case it is a new unit or properties exported on the bus have changed. This should prevent unnecessary DBus wakeups and associated DBus traffic when device_setup_unit() was called while reparsing /proc/self/mountinfo due to the mountinfo notifications. Note that we parse /proc/self/mountinfo quite often on the busy systems (e.g. k8s container hosts) but majority of the time mounts didn't change, only some mount got added. Thus we don't need to generate PropertiesChanged for devices associated with the mounts that didn't change. Thanks to Renaud Métrich <rmetrich@redhat.com> for debugging the problem and providing draft version of the patch.
