Update the saved power state after checking the restore policy

If the power state changes while power control is not running
(e.g. during BMC boot), the stored state can be left stale
causing it to behave incorrectly on a power-loss.

For example:
   1. The system is shut down and the 'Off' state is saved.
   2. The BMC is rebooted.
   3. The power button is used to boot the system.
   4. Power control will start with 'On' as the current state,
      but with 'Off' still as the saved state.
   5. The system loses power.
   6. On restore, the previous state should be detected as 'On',
      but is instead detected as 'Off'.

This change updates the saved power state to match the current
state after checking the restore policy.

Tested:
Ran the scenario above and confirmed that the system correctly
detected and restored the 'On' state in step 6.
