ipa: rpi: alsc: Do not re-read the alsc.status metadata
This was being re-read in order to determine what LSC gains had been applied. We can just retrieve these numbers from the prevAsyncResults_ instead. This will also enable other future algorithms to manipulate the LSC tables in the alsc.status, without it breaking the core ALSC algorithm here.
