[swss service] flush fast-reboot enabled flag upon swss stopping (#3908)

Browse Source 
If we need to stop swss during fast-reboot procedure on the boot up path,
it means that something went wrong, like syncd/orchagent crashed already,
we are stopping and restarting swss/syncd to re-initialize. In this case,
we should proceed as if it is a cold reboot.
