NCD4_dumpbytes: use correct swapline for object size

Browse Source 
This addresses a type-punning warning in gcc:
gcc11 warns about one of the strict aliasing violations:
d4util.h:44:7: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
   44 |     *((unsigned int*)ip) = u.i; \
      |      ~^~~~~~~~~~~~~~~~~~
d4dump.c:51:13: note: in expansion of macro 'swapinline32'
   51 |             swapinline32(v.u64);
      |             ^~~~~~~~~~~~
