libpayload: ahci: Fix command engine shutdown
A timeout while waiting for a device' signature has shown that our error path wasn't correct. The shutdown of the ports command engine always timed out. Fix that by waiting for FR (FIS Receive Running) to be cleared independently from CR (Command List Running) and after clearing FRE (FIS Receive Enable).
