The len and is_write arguments to cpu_physical_memory_unmap() were
swapped.  This patch changes calls to use the correct argument ordering.

cdfe17df88 ahci: delete write-only variables (v2)
Avoid these warnings with GCC 4.6.0:
/src/qemu/hw/ide/ahci.c: In function 'ahci_reset_port':
/src/qemu/hw/ide/ahci.c:810:14: error: variable 'tfd' set but not used [-Werror=unused-but-set-variable]
/src/qemu/hw/ide/ahci.c: In function 'handle_cmd':
/src/qemu/hw/ide/ahci.c:1103:19: error: variable 'pr' set but not used [-Werror=unused-but-set-variable]

In the tfd variable case, fix the logic also.

f6ad2e32f8 ahci: add ahci emulation
This patch adds an emulation layer for an ICH-9 AHCI controller. For now
this controller does not do IDE legacy emulation. It is a pure AHCI controller.
