Revert "drm/syncobj: Fix handle <-> fd ioctls with dirty stack" 



This reverts commit 2e3649e2.

The problem occurs when userspace is compiled against new headers
with new members, but don't correctly initialise those new members.

This is not a kernel problem, and should be fixed in userspace by
correctly zero'ing all members.
