netfilter: arp_tables: remove redundant check on ret being non-zero
ret is initialized to zero and if it is set to non-zero in the xt_entry_foreach loop then we exit via the out_free label. Hence the check for ret being non-zero is redundant and can be removed. Detected by CoverityScan, CID#1357132 ("Logically Dead Code") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
