ACPI / processor: Get power info before updating the C-states

commit f427e5f1cf75bba84cccdac1d8a90552d9ae1065 upstream.

acpi_processor_get_power_info() has to be called before
acpi_processor_setup_cpuidle_states() to have the latest
information available. This fixes the missing C-state information
after AC-->DC transition.
