soc: intel_adsp/ace: fix CPU halting

Browse Source 
() The check for whether the CPU is already active before halting
   was incorrect. It should only fail if the CPU is not active,
   but the CHECKIF() conditional was inverted. So invert it.

() Also need to set the entry in the bookkeeping array to false
   once a CPU is considered powered down.
