Since size has been aligned to PAGE_SIZE already, just align it
to PAGE_SIZE so later the buffer can be used as a texture in mesa
after https://cgit.freedesktop.org/mesa/mesa/commit/?id=f7a4051b8
Otherwise, si_texture_create_object will fail at line
"buf->alignment < tex->surface.alignment"
I don't think that those Mesa checks are a good idea in the first place.
The alignment value is often specified as zero when it doesn't matter
because the minimum alignment can never be less than the page size.
