Subject: [PATCH] device: Fix not handling initiator properly
Previously initiator would be set whenever a central key was found
which turns out to be unreliable besides the MGMT New Connection event
does in fact inform if the connection was initiated locally or not.
Fixes: https://github.com/bluez/bluez/issues/598
