CHROMIUM: Revert "drm/syncobj: Stop reusing the same struct file for all syncobj -> fd"

This reverts commit 5fb252cad61f20ae5d5a8b199f6cc4faf6f418e1.

Revert in preparation for merge of v4.14.31 into chromeos-4.14.
The patch causes substantial conflicts due to local changes made
on top of v4.14. If it is needed, it will have to be pulled in manually.

TEST=Merge into chromeos-4.14 without merge conflicts
