fix: ahci: fixed failure on write (clear IRQ before flush)
When scsi_write is called via aHCI, it tries to flush the
drive cache, and it failed.
The cache flush failed because the IRQ status register
wasn't cleared after previous transaction.
- clear the SATA IRQ status register before the cache flush
- Fixed JIRA:SYSTEMSW-1532.
