net/ipv6/addrconf: simplify sysctl registration
Struct ctl_table_header holds pointer to sysctl table which could be used for freeing it after unregistration. IPv4 sysctls already use that. Remove redundant NULL assignment: ndev allocated using kzalloc. This also saves some bytes: sysctl table could be shorter than DEVCONF_MAX+1 if some options are disable in config.
