host-bmc: Fix D-Bus property signal of sendStateSensorEvent method
host-bmc: Fix D-Bus property signal of sendStateSensorEvent method

When using the propertiesChanged method to monitor the D-Bus property
signal change, we have to verify the property name first, otherwise,
it may also trigger this method and send an event message to Host
when we set other property values under the same interface.
This is wrong logic.
