cpufreq: Correct the data reported in all_time_in_state

Commit bd9474e059bbb2bb62f7e93894cfc3d3ba473fb2 (cpufreq_stats:
Adds the fucntionality to load current values for each frequency
for all the cores) introduced a change by which
'cpufreq_allstats_create' gets called at initialization (from
'cpufreq_stats_init' instead of 'cpufreq_stat_notifier_policy').
This causes 'cpufreq_allstate_create' to be called before the
freq_table is allocated from 'create_all_freq_table'. Due to
this, the data for cpu's which are online at boot are not
added to the 'all_freq_table' leading to the incorrect
reporting of data when the below sysfs command is run -
'cat sys/devices/system/cpu/cpufreq/all_time_in_state'.

Correct this behaviour by altering the cpufreq_stats init
sequence by which the memory for 'all_freq_table' is allocated
before the 'cpufreq_allstats_create' function is called.
