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