[Libva] [PATCH intel-driver 04/13] vebox: fix order of submitted commands.

[Gwenole Beauchesne]

For each frame, the Intel HD Graphics hardware specification mandates
that the following commands should be submitted, in-order: VEBOX_STATE,
VEBOX_SURFACE_STATE(input), VEBOX_SURFACE_STATE(output), VEB_DI_IECP.
