[Libva] [PATCH ] Fix inconsistent surface dimension during allocating surface buffer object

[yakui.zhao at intel.com]

From: Zhao Yakui <yakui.zhao at intel.com>

When one surface is created, the height/width is aligned to 16 pixels.
But when trying to allocate the buffer object for it, the width is aligned
to 128 and height is aligned to 32. If the surface is mapped and accessed
before allocating the buffer object, the incorrect dimension is returned and
and the incorrect content is written.
