ALSA: hda - More relax for pending period handling
Since the pending periods are often bogus and take long time until actually processed, it often results in a high CPU usage of the hd-audio workq. Overall it's better to have low CPU consumption by avoiding a too tight loop rather than the wake-up timing accuracy. Signed-off-by: Takashi Iwai <tiwai@suse.de>
