thermal: devfreq: Check OPP for errors
It is possible for dev_pm_opp_find_freq_exact() to return errors. It was
all fine earlier as dev_pm_opp_get_voltage() had a check within it to
check for invalid OPPs, but dev_pm_opp_put() doesn't have any similar
checks and the callers need to make sure OPP is valid before calling
them.
Also update the later dev_warn_ratelimited() to not print the error
message as the OPP is guaranteed to be valid now.
