ALSA: pcm core - Avoid jiffies check for devices with BATCH flag
The hardware devices with SNDRV_PCM_INFO_BATCH flag can't give the
precise current position. And such hardwares have often big FIFO
in addition to the ring buffer, and it screws up the jiffies check
in pcm_lib.c.
This patch adds a simple check of info flag so that the driver skips
the jiffies check in snd_pcm_period_elapsed() when BATCH flag is set.
