    sna: Reserve relocation entries for the deferred VBO

    Whilst we reserved exec entry slots for the deferred VBO, there were no
    relocation spaces reserved. So if we submitted a render command followed
    by a multitude of BLT copies, we could then overrun the relocation array
    when adding the deferred vbo to the batch.
