Subject: PM / Domains: Fix unsafe iteration over modified list of domain providers

From: Krzysztof Kozlowski <krzk@xxxxxxxxxx>

commit b556b15dc04e9b9b98790f04c21acf5e24f994b2 upstream.

of_genpd_del_provider() iterates over list of domain provides and
removes matching element thus it has to use safe version of list
iteration.
