[PATCH 3/4] x86: Remove __current_clr_polling() from mwait_idle()

[Frederic Weisbecker <frederic@kernel.org>]

mwait_idle() is only ever called through by cpuidle, either from
default_idle_call() or from cpuidle_enter(). In any case
cpuidle_idle_call() sets again TIF_NR_POLLING after calling it so there
is no point for this atomic operation upon idle exit.
