PM: ACPI: Output correct message on target power state

commit a9b760b0266f563b4784f695bbd0e717610dc10a upstream.

Transitioned power state logged at the end of setting ACPI power.

However, D3cold won't be in the message because state can only be
D3hot at most.

Use target_state to corretly report when power state is D3cold.
