Subject: [PATCH] Revert "sched, x86: Optimize branch hint in __switch_to()"

This reverts commit a3a1de0c34de6f5f8332cd6151c46af7813c0fcb.

Commit 8ec6993d9f7d961014af970ded57542961fe9ad9 cleared the es and ds
selectors, so the original branch hints are correct now. Therefore
the branch hint doesn't need to be removed.
