Now that we can use -EPROBE_DEFER, it's no longer required to spin off the snd_hdac_i915_init into a workqueue.
Use the -EPROBE_DEFER mechanism instead, which must be returned in the probe function.
Changes since v1: - Use dev_err_probe() - Don't move probed_devs bitmap unnecessarily. (tiwai) - Use goto out_azx_free after cleanup of error path. (tiwai) - Move snd_hdac_i915_init slightly upward, to ensure it's always initialised before vga-switcheroo is called.
