ACPI: processor: idle: Remove redundant pr->power.count assignment

pr->power.count stands for the number of valid processor cstates. And it
is correctly set with the return value of acpi_processor_power_verify(),
in acpi_processor_get_cstate_info().

Remove the redundant logic that unnecessarily overrides pr->power.count
value.

No functional change intended.
