OPP: Check for invalid OPP in dev_pm_opp_find_level_ceil()
_find_key_ceil() may return an error and that must be checked before passing the same to dev_pm_opp_put(). Fixes: 41907aa4ae37 ("OPP: Level zero is valid") Reported-by: Dan Carpenter <dan.carpenter@linaro.org> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
