i9082: enable KSM by default

I am sure there are users who don't care about KSM or even know about KSM. Provided with the warning as soon as they open the "Performance" option in Settings, "Proceed with caution bla bla...", many may think twice before enabling KSM.

You have already enabled the flag in the kernel for KSM.

This patch just enables it by default to give some Performance boost to those who aren't too educated about KSM.

Support for this has already been merged: http://review.cyanogenmod.org/#/c/57256/
