Fix CR_RESPONSE mangaement message using wrong key_id

Fix CR_RESPONSE mangaement message using wrong key_id

the management interface expects the management key id instead
of the openvpn key id. In the past they often were the same for low ids
which hid the bug quite well.

Also do not pick uninitialised keystates (management key_id is not valid
in these).

Patch v2: do not add logging
