netlink: Call cb->done from a worker thread

[ Upstream commit 707693c8a498697aa8db240b93eb76ec62e30892 ]

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.
