Unlock in6_ioctl_get() aka. SIOCGIF{DSTADDR,NETMASK,AFLAG,ALIFETIME}_IN6

First the right address is picked from the net lock protected if_addrlist. Then all ioctls just copy out the address, nothing requires the kernel lock. SIOCGIFDSTADDR_IN6 checks the net lock protected if_flags, SIOCGIFALIFETIME_IN6 computes lifetimes which only need the address. Users of these io
