vf_vavpp: allocate output surfaces with the same size as input

This can happen if the hw decoder allocates padded surfaces (e.g.
mod16), but the VPP output surface was allocated with the exact size.
Apparently VPP requires matching input and output sizes, or it will add
artifacts. In this case, it added mirrored pixels to the bottom few
pixels.

Note that the previous commit should have fixed this. But it didn't
work, while this commit does.

Fixes #2320.
