    cpufreq: Remove cpufreq_frequency_get_table() · f8bfc116

    Most of the callers of cpufreq_frequency_get_table() already have the
    pointer to a valid 'policy' structure and they don't really need to go
    through the per-cpu variable first and then a check to validate the
    frequency, in order to find the freq-table for the policy.
    
    Directly use the policy->freq_table field instead for them.
    
    Only one user of that API is left after above changes, cpu_cooling.c and
    it accesses the freq_table in a racy way as the policy can get freed in
    between.
    
    Fix it by using cpufreq_cpu_get() properly.
    
    Since there are no more users of cpufreq_frequency_get_table() left, get
    rid of it.
