[media] saa7134: fix warning with !MEDIA_CONTROLLER

When CONFIG_MEDIA_CONTROLLER is disabled, we get a warning
about an unused function:

drivers/media/pci/saa7134/saa7134-core.c:832:13: error: 'saa7134_create_entities' defined but not used [-Werror=unused-function]

This moves the #ifdef outside of the function, as it is
never called here.
