[RFC PATCH v4 7/7] sched: fine-tune SD_MC_INIT -- revert

[Vaidyanathan Srinivasan <svaidy@linux.vnet.ibm.com>]

commit 14800984706bf6936bbec5187f736e928be5c218
    Author: Mike Galbraith <efault@gmx.de>
    Date:   Fri Nov 7 15:26:50 2008 +0100

    Reverting this patch for now since this affects
    consolidation and power savings.  Will rework
    this tuning in the next iteration.

    Tune SD_MC_INIT the same way as SD_CPU_INIT:
    unset SD_BALANCE_NEWIDLE, and set SD_WAKE_BALANCE.

    This improves vmark by 5%:
