This fixes compilation errors in case nvenc is enabled (e.g. autodected) with both nvenc-based encoders disabled because nvenc uses ff_alloc_a53_sei(), yet only the nvenc-based encoders require atsc_a53. (This error does not manifest itself in case of static linking (nothing pulls in nvenc.o), but it exists with shared builds.)
