PM / Domains: Fix unsafe iteration over modified list of domains
commit a7e2d1bce4c1db471f1cbc0c4666a3112bbf0994 upstream.
of_genpd_remove_last() iterates over list of domains and removes
matching element thus it has to use safe version of list iteration.
Fixes: 17926551c98a (PM / Domains: Add support for removing nested PM domains by provider)
