PM / Domains: Fix unsafe iteration over modified list of domain providers
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.
Fixes: aa42240ab254 (PM / Domains: Add generic OF-based PM domain look-up)
