[PATCH][next] virtio_vdpa: remove redundant check on desc

[Colin Ian King]

The boolean variable has_affinity is true when desc is non-null and
ops->set_vq_affinity is non-null. Hence the call to create_affinity_masks
does not need to check for desc being non-null is redundant when
has_affinity is true, so it can be removed as well as the now unused
default_affd.
