[PATCH 2/4] ALSA: pci: emu10k: delete usage of 'struct snd_pcm_runtime.sync'

[Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>]

In Linux kernel version 4.13, the data of snd_pcm_sync_id union is not
exposed to user space by a commit e11f0f90a626 ("ALSA: pcm: remove
SNDRV_PCM_IOCTL1_INFO internal command"). From then, we have received
no issues from users or developers for emu10k.

This commit deletes the usage of 'struct snd_pcm_runtime.sync' from the
driver.
