[PATCH 1/1] ipv6: remove unnecessary condition judgement

[Zhu Yanjun <zyjzyj2000@gmail.com>]

The "init_net" condition judgement in function addrconf_exit_net is introduced
in commit 44a6bd29 [Create ipv6 devconf-s for namespaces] to avoid freeing
init_net. In commit c900a800 [ipv6: fix bad free of addrconf_init_net],
function addrconf_init_net will allocate memory for every net regardless of
init_net. In this case, it is unnecessary to make "init_net" condition judgement.
