ident: fix undefined variable when NO_IPV6 is set

Browse Source 
Commit 00bce77 (ident.c: add support for IPv6, 2015-11-27)
moved the "gethostbyname" call out of "add_domainname" and
into the helper function "canonical_name". But when moving
the code, it forgot that the "buf" variable is passed as
"host" in the helper.
