cpufreq: ACPI: Remove unused variables 'acpi_cpufreq_online' and 'ret'

Browse Source 
Clang warns:

  drivers/cpufreq/acpi-cpufreq.c:970:24: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized]
          acpi_cpufreq_online = ret;
                                ^~~
  drivers/cpufreq/acpi-cpufreq.c:960:9: note: initialize the variable 'ret' to silence this warning
          int ret;
                ^
                  = 0
  1 error generated.

Both ret and acpi_cpufreq_online are now unused so they can be safely
removed, clearing up the warning.
