Subject: [PATCH] Revert "sched: Add missing call to calc_load_exit_idle()"

This reverts commit 900404e5d201d0a6d2806f615b41e939713d55db on 3.5,
which is commit 749c8814f08f12baa4a9c2812a7c6ede7d69507d upstream.

The change was originally intended to fix a mismerge in 3.6. The 3.5
stable branch was unaffected by the issue, as reported by Huacai Chen on
stable mailing list (on the thread 'Seems like "sched: Add missing call
to calc_load_exit_idle()" should be reverted in 3.5 branch').

As concluded by Peter Zijlstra:
"(...) You are right, v3.5.5 has one calc_load_exit_idle() too many, the
one in tick_nohz_update_jiffies() needs to go. (...)"
