Mark Johnston 7a78ae8865 netlink: Zero-initialize writer structures allocated on the stack 
The prevailing pattern seems to be to simply initialize all fields to
zero.  Without this, it's possible to trigger a branch on uninitialized
memory, specifically, when testing nw->ignore_limit in
nlmsg_refill_buffer().

Initialize the writer structure in a couple of functions where this is
necessary.
