UBUNTU: SAUCE: Revert "x86, hibernate: Initialize mmu_cr4_features during boot"

This reverts commit 60d3abc3a55c37376c989e65f87fe25f78281793.

Since the update to 2.6.38.3, this fix isn't needed, as the problematic
commit ("x86: Cleanup highmap after brk is concluded") which required it
got reverted. To keep things clean, revert the fix too.
