[CPUFREQ] update Doc for cpuinfo_cur_freq and scaling_cur_freq 

I think the way "cpuinfo_cur_info" and "scaling_cur_info" are defined under
./Documentation/cpu-freq/user-guide.txt can be enhanced. Currently, they are
both defined the same way: "Current speed/frequency" of the CPU, in KHz".

Below is a patch that distinguishes one from the other.

Regards,

-----------------------------------------
Update description for "cpuinfo_cur_freq" and "scaling_cur_freq".

Some of the wording is drawn from comments found in
./drivers/cpufreq/cpufreq.c: cpufreq_out_of_sync():

 *      @old_freq: CPU frequency the kernel thinks the CPU runs at
 *      @new_freq: CPU frequency the CPU actually runs at
