Set the sof_data->sof_probe_complete callback unconditionally of CONFIG_SND_SOC_SOF_PROBE_WORK_QUEUE. The sof_probe_complete will be called when the sof_probe_continue() function is successfully executed, called either directly from snd_sof_device_probe() or from the scheduled work. Since all error cases within the call chain of snd_sof_device_probe() have error prints, there is no need to print again in the acpi/pci/of level.
