PEL: Change method of asserting a fault LED

There was a recent change in direction on how PELs should request that
fault LEDs be turned on.  Previously, the code would talk to the LED
group objects directly.  The new direction is to set the Functional
property on the OperationalStatus interface on the inventory objects in
question to false, and the LED manager code will watch that to know when
to turn on the LEDs.
