  log: |2
     Fixes a problem that some driver(e.g. acpitz(4) or coretemp(5)) which
    use sysmon_envsys sleep waiting at "rndsrc" when "drvctl -d".
    Don't call rnd_detach_source() in sme_remove_event() which is called
    from sme_event_unregister_all(). Instead, call rnd_detach_source() in
    sysmon_envsys_sensor_detach() and call sysmon_envsys_sensor_detach()
    before sme_event_unregister_sensor(). Each sensor(envsys_data) has each
    rnd_src, but some sme_events point to the same rnd_src in a sensor.
    Calling rnd_detach_souce() twice with the same rnd_src brokes a reference
    count in rnd_src. OK'd by pgoyette@.
