[PATCH 1/3] ASoC: SOF: pm: Set target state earlier

If the DSP crashes before the system suspends, the setting of target state
will be skipped because the firmware state will no longer be
SOF_FW_BOOT_COMPLETE. This leads to the incorrect assumption that the
DSP should suspend to D0I3 instead of suspending to D3. To fix this,
set the target_state before we skip to DSP suspend even when the DSP has
crashed.
