With misconfigured mysql, which uses Restart=always, the following two
messages would loop indefinitely and the "systemctl start" would never
finish:
  Job pending for unit, delaying automatic restart.
  mysqld.service holdoff time over, scheduling restart.

In service_enter_dead() always set the state to SERVICE_FAILED/DEAD first
before setting SERVICE_AUTO_RESTART. This is to allow running jobs to
complete. OnFailure will be also triggered at this point, so there's no
need to do it again from service_stop() (where it was added in commit
f0c7b229).

Note that OnFailure units should better trigger only after giving up
auto-restarting, but that's for another patch to solve.
