[PATCH -next] cpufreq: Remove the unused variables

[Yang Li]

The function using variable 'acpi_cpufreq_online' has been deleted,
so it is redundant. Similarly, variable 'ret' assigned to
acpi_cpufreq_online is redundant, and 'ret' is not initialized,
because its assignment statement has also been eliminated.

Remove the unused variables to silence this warning:
drivers/cpufreq/acpi-cpufreq.c:960:9: note: initialize the variable
'ret' to silence this warning
