[PATCH 9/13] ALSA: i2sbus: Delete an unnecessary check before the function call "snd_pcm_suspend_all

The snd_pcm_suspend_all() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
