I'd call this [cleanup] not [func], it's not in any way a user-visible
change.

To quibble, I'd suggest moving it to lib/dns/nsec3.c and calling the
function dns_nsec3param_salttotext().  The files in lib/dns/rdata are
referenced via #include in code.c and called from lib/dns/rdata.c; it
isn't a good fit to mix other stuff there.
