From: Wei Yongjun <weiyongjun1@huawei.com>
Since we will remove items off the list using list_del() we need
to use a safe version of the list_for_each() macro aptly named
list_for_each_safe().
This is detected by Coccinelle semantic patch.
Fixes: b8c722ddd548 ("ASoC: Intel: Skylake: Add support for deferred
DSP module bind")
