Revert "intel: Fix the client-side swapbuffers throttling."

This reverts commit 76360d6abc9e0195bc5c373101ae616e68b2e6e6.  On
second thought, it turned out that sync objects also used the
wait_rendering API like this, and would need the same treatment, and
so wait_rendering itself is fixed in libdrm now.
