3.2.85-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Mathias Krause <minipli@xxxxxxxxxxxxxx>
commit f567e950bf51290755a2539ff2aaef4c26f735d3 upstream.
To avoid having dangling function pointers left behind, reset calcit in
rtnl_unregister(), too.
This is no issue so far, as only the rtnl core registers a netlink
handler with a calcit hook which won't be unregistered, but may become
one if new code makes use of the calcit hook.
