ACPI: Fix thermal shutdowns

commit 9f497bcc695fb828da023d74ad3c966b1e58ad21 upstream

ACPI: Fix thermal shutdowns

Do not use unsigned int if there is test for negative number...

See drivers/acpi/processor_perflib.c
  static unsigned int ignore_ppc = -1;
...
  if (event == CPUFREQ_START && ignore_ppc <= 0) {
       ignore_ppc = 0;
...
