[PATCH v1] PM: EM: Decrement policy counter

[Pierre Gondois]

From: Pierre Gondois <Pierre.Gondois@xxxxxxx>

Fixes: e458716a92b57 ("PM: EM: Mark inefficiencies in CPUFreq")
In the above commit, cpufreq_cpu_get() is called without
a cpufreq_cpu_put(), permanently increasing the reference counts
of the policy struct.
Decrement the reference count once the policy struct is not used
anymore.
