cpufreq: Drop policy locking from cpufreq_policy_is_good_for_eas()
Policy locking was added to cpufreq_policy_is_good_for_eas() by commit
4854649b1fb4 ("cpufreq/sched: Move cpufreq-specific EAS checks to
cpufreq") to address a theoretical race condition, but it turned out to
introduce a circular locking dependency between the policy rwsem and
sched_domains_mutex via cpuset_mutex. This leads to a board lockup on
OdroidN2 that is based on the ARM64 Amlogic Meson SoC.
Drop the policy locking from cpufreq_policy_is_good_for_eas() to address
this issue.
Fixes: 4854649b1fb4 ("cpufreq/sched: Move cpufreq-specific EAS checks to cpufreq")
