addrconf: always initialize sysctl table data
When sysctl performs restrict writes, it allows to write from
a middle position of a sysctl file, which requires us to initialize
the table data before calling proc_dostring() for the write case.
Fixes: 3d1bec99320d ("ipv6: introduce secret_stable to ipv6_devconf")
