netlink: Call cb->done from a worker thread
The cb->done interface expects to be called in process context.
This was broken by the netlink RCU conversion. This patch fixes
it by adding a worker struct to make the cb->done call where
necessary.
Fixes: 21e4902aea80 ("netlink: Lockless lookup with RCU grace...")
