[Libva] [PATCH] va/x11: Require synchronisation to vblank with DRI2SwapBuffers

[Xiang, Haihao]

But in Lukas's comment:

"Had to revert it because of number of hard lockups."

Did you have other patch to fix the lockup issue in other component or
does the issue has gone away? If not, We have to revert the patch
otherwise user will suffer lockup issue with libva.

Thanks
Haihao
