[ALSA] hda_intel: fix unexpected ring buffer positions
I found two issues with ICH7-M (it should be related to other HDA chipsets as well): - the ring buffer position is not reset when stream restarts (after xrun) - solved by moving azx_stream_reset() call from open() to prepare() callback and reset posbuf to zero (it might be filled with hw later than position() callback is called) - irq_ignore flag should be set also when ring buffer memory area is not changed in prepare() callback - this patch replaces irq_ignore with more universal check based on jiffies clock Signed-off-by: Jaroslav Kysela <perex@perex.cz>
