Replace the last few print_host() calls with print_addr() ones.

Replace the last few print_host() calls with print_addr() ones.

In most cases print_host(addr, buf, buflen) can be replaced with
strlcpy(buf, print_addr(addr), buflen).
Some code was never fully adjusted to the full power of print_host() and
there are remnants of times well before print_host() supported multiple
internal buffers.
