sched / idle: Call idle_set_state() from cpuidle_enter_state()
Introduce a wrapper function around idle_set_state() called
sched_idle_set_state() that will pass this_rq() to it as the
first argument and make cpuidle_enter_state() call the new
function before and after entering the target state.
At the same time, remove direct invocations of idle_set_state()
from call_cpuidle().
This will allow the invocation of default_idle_call() to be
moved from call_cpuidle() to cpuidle_enter_state() safely
and call_cpuidle() to be simplified a bit as a result.
