volser: More renaming of putshort and putint32

Commit 2d6bc153689f14f8690878b15d9fb711a56b0546 renamed the putshort
and putint32 macros in dumpstuff.c to avoid conflicts with macros
that are defined in resolv.h. However, an almost identical copy of
that code also exists in vol-dump.c

Rename putshort and putint32 there too.
