Subject: Zero out grp before re-using it (new ones are already cleared by
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=86445948da4b03a0b6fa3494f5ac7b80af6a7263;p=openbsd

Zero out grp before re-using it (new ones are already cleared by
calloc).   We only reuse grp when there is an unresolvable host.
Fixes a bug where if a host in a netgroup is unresolvable then
entire netgroup is ignore.  OK krw@
