[PATCH] conntrackd UDP IPv6 destination address not usable (Bug 1378)

[Jan-Martin Raemer <raemer@xxxxxxxxxx>]

Hi,

as reported in https://bugzilla.netfilter.org/show_bug.cgi?id=1378,
conntrackd refuses to start with a vaild IPv6_Destination_Address,
reporting "inet_pton(): IPv6 unsupported" due to a forgotten handling of
err>0 (i.e. success). This patch fixes the issue:
