cpufreq: Don't skip cpufreq_frequency_table_cpuinfo()

The commit 6db0f53 ("cpufreq: preserve freq_table_sorted
across suspend/hibernate") unintentionally made a change where
cpufreq_frequency_table_cpuinfo() isn't getting called anymore
for old policies getting re-initialized.

This leads to potentially invalid values of policy->max and
policy->cpuinfo_max_freq.

Fix the issue by reverting the original commit and adding the condition
for just the sorting function.
