cpufreq: ia64: Fix a memory leak in acpi_cpufreq_cpu_exit

From: Pan Xinhui <[email protected]>

freq_table should be alloced in ->init and freed in ->exit. However it does not be freed. Fix this memory leak in acpi_cpufreq_cpu_exit.

hi, all
ia64-acpi-cpufreq has similar issues with acpi-cpufreq. Maybe we need make other two patches.
Replace struct cpufreq_acpi_io *acpi_io_data[NR_CPUS] with policy->driver_data, and Fix an acpi perf unregister issue.

As two patches
[1/2] Drop the unused first argument of acpi_processor_unregister_performance(). [2/2] Drop the now redundant acpi_data pointer from acpi_cpufreq_data.
are going into the kernel tree, If I send my patches to you now, there will be some conflicts.

So I may wait for a couple of days until all previous patches merged into kernel tree.

thanks

Queued up for 4.3, thanks!
