Viresh Kumar 7cd7b56037 thermal: cpu_cooling: Avoid accessing potentially freed structures ...

commit 289d72afdd upstream.

After the lock is dropped, it is possible that the cpufreq_dev gets
freed before we call get_level() and that can cause kernel to crash.

Drop the lock after we are done using the structure.
