Subject: [PATCH V2 01/12] OPP: Free OPP table properly on performance state irregularities

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.

Cc: 4.18 <stable@...r.kernel.org> # v4.18
Fixes: 3ba98324e81a ("PM / OPP: Get performance state using genpd helper")
