ALSA: hda - Fix complete_all() timing in deferred probes
When the probe of snd-hda-intel driver is deferred due to f/w loading or the nested module loading, complete_all() should be also delayed until the initialization really finished. Otherwise, vga-switcheroo client would start switching before the actual init is done. Signed-off-by: Takashi Iwai <tiwai@suse.de>
