[PATCH -next] ASoC: Intel: Skylake: Fix to use list_for_each_safe() when delete items

[Wei Yongjun]

From: Wei Yongjun <weiyongj...@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")
