ahci: fix notification handling
Asynchronous notification on ICH9 didn't work because it didn't write
AN FIS into the RX area - it only updates SNotification. Also,
snooping SDB_FIS RX area is racy against further SDB FIS receptions.
Let sata_async_notification() determine using SNTF if it's available
and snoop RX area iff SNTF isn't available
