netlink: Do not schedule work from sk_destruct

[ Upstream commit ed5d7788a934a4b6d6d025e948ed4da496b4f12e ]

It is wrong to schedule a work from sk_destruct using the socket
as the memory reserve because the socket will be freed immediately
after the return from sk_destruct.

Instead we should do the deferral prior to sk_free.

This patch does just that.
