Subject: addrconf: always initialize sysctl table data

From: WANG Cong <[email protected]>

[ Upstream commit 5449a5ca9bc27dd51a462de7ca0b1cd861cd2bd0 ]

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.
