Subject: [PATCH] Fix compiler error introduced with recent IPv6 commit.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit 76350316de38 ("Handle IPv6 interfaces correctly.") added
a string copy that creates this gcc-11 error message:

> gcc-11 -O2 -g -Wall -Werror -Wextra -fvisibility=hidden -fPIC -I/usr/include/kmod    -c -o idbm.o idbm.c
> idbm.c: In function ‘_idbm_node_rec_link’:
> idbm.c:999:17: error: ‘strncpy’ specified bound 65 equals destination size [-Werror=stringop-truncation]
>   999 |                 strncpy((*node).iface.name, iface_name, ISCSI_MAX_IFACE_LEN);
>       |                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So copy one less character, maximum.
