ipv6: fix rtnl locking in setsockopt for anycast and multicast
commit a9ed4a2986e13011fcf4ed2d1a1647c53112f55b upstream.
Calling setsockopt with IPV6_JOIN_ANYCAST or IPV6_LEAVE_ANYCAST
triggers the assertion in addrconf_join_solict()/addrconf_leave_solict()
ipv6_sock_ac_join(), ipv6_sock_ac_drop(), ipv6_sock_ac_close() need to
take RTNL before calling ipv6_dev_ac_inc/dec. Same thing with
ipv6_sock_mc_join(), ipv6_sock_mc_drop(), ipv6_sock_mc_close() before
calling ipv6_dev_mc_inc/dec.
This patch moves ASSERT_RTNL() up a level in the call stack.
