[PATCH] intel_idle: fix intel_idle_state_needs_timer_stop build failure

[Arnd Bergmann]

From: Arnd Bergmann <a...@arndb.de>

The newly added function is defined inside of an #ifdef section but
used outside, leading to a build failure:

drivers/idle/intel_idle.c:1510:7: error: implicit declaration of function 
'intel_idle_state_needs_timer_stop' [-Werror,-Wimplicit-function-declaration]
                if 
(intel_idle_state_needs_timer_stop(&drv->states[drv->state_count]))
                    ^

Move it ahead of the CONFIG_ACPI_PROCESSOR_CSTATE check.

Fixes: 6e1d2bc675bd ("intel_idle: Fix intel_idle() vs tracing")
