[PATCH 4.19 196/361] OPP: Free OPP table properly on performance state irregularities

From: Viresh Kumar <viresh.kumar@linaro.org>

commit 2fbb8670b4ff4454f1c0de510f788d737edc4b90 upstream.

The OPP table was freed, but not the individual OPPs which is done from
_dev_pm_opp_remove_table(). Fix it by calling _dev_pm_opp_remove_table()
as well.
