Log:
  [aacraid] Add missing unmap call for SYNC mode
  
  This issue was observed on a PowerPC64 machine with an Adaptec RAID Controller
  with PCI device ID 0x028d. After several read/write operations, the kernel was
  panic'ing in bus_dmamap_sync(). This was due to a missing aac_unmap_command()
  in the SYNC path.
