[PATCH for-8.2] hw/s390x/s390-virtio-ccw: Remove superfluous code to set the NIC model

[Thomas Huth <thuth@redhat.com>]

The check for nd->model being NULL was originally required, but in
commit e11f463295d95aba ("s390x/virtio: use qemu_check_nic_model()")
the corresponding code had been replaced by a call to the function
qemu_check_nic_model() - and this in turn calls qemu_find_nic_model()
which contains the same check for nd->model being NULL again. So we
can remove this from the calling site now.
