cpufreq: mediatek-hw: Fix wrong return value in mtk_cpufreq_get_cpu_power()
commit 172bf5ed04cb6c9e66d58de003938ed5c8756570 upstream.
mtk_cpufreq_get_cpu_power() return 0 if the policy is NULL. Then in
em_create_perf_table(), the later zero check for power is not invalid
as power is uninitialized. As Lukasz suggested, it must return -EINVAL when
the 'policy' is not found. So return -EINVAL to fix it.
