Subject: [PATCH] systemd-core: nop_job of a unit must also be coldpluged
after deserization.
When a unit is not in-active, and systemctl try-restart is executed for
this unit,
systemd will do nothing for it and just accept it as a nop_job for the
unit.
When then nop-job is still in the running queue, then daemon-reload is
performed, this nop job
will be dropped from the unit since it is not coldpluged in the
unit_coldplug function.
After then, the systemctl try-restart command will hang forever since no
JOB_DONE dbus signal will be sent
to it from systemd.
This patch fix this problem by do coldplug for the nop_job in
unit_coldplug function.
