From: Lev Stipakov <l...@openvpn.net>
This patch fixes "unused variable/unreferenced format parameter"
warnings in different places, kudos to Visual Studio compiler
for discoveing some of those.
This also also removes unneeded uninit_management_callback_multi()
wrapper.
Signed-off-by: Lev Stipakov <l...@openvpn.net>
