check requested state before update properties

When the power policy is "Restore" or "Always-Off", software only
updates properties if current requested state is "On". This action is
necessary to avoid redundant tasks when AC power.

Tested:
     1.  Turn Off the HOST and set power policy to Always-Off
         ipmitool chassis power off
         ipmitool chassis policy always-off
     2.  AC power, wait until BMC has been rebooted.
     3.  HOST is OFF, check journalctl log.
         BMC did not request to update requested state.
     4.  Turn On the HOST, AC power, wait until BMC has been rebooted.
     5.  HOST is OFF, check journalctl log.
         BMC requests to update requested state to "Off".
     6.  Set power policy to Previous.
         ipmitool chassis policy previous
     7.  AC power, wait until BMC has been rebooted.
     8.  HOST is OFF, check journalctl log.
         BMC did not request to update requested state.
     9.  Turn On the HOST, AC power, wait until BMC has been rebooted.
     10. HOST is ON, check journalctl log.
         BMC requests to update requested state to "On".
