[PATCH] cpufreq: armada-8k: Fix off by one in armada_8k_cpufreq_free_table()

[Dan Carpenter]

The freq_tables[] array has num_possible_cpus() elements so, to avoid an
out of bounds access, this loop should be capped at "< nb_cpus" instead
of "<= nb_cpus".  The freq_tables[] array is allocated in
armada_8k_cpufreq_init().
