From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This makes MGMT_OP_LOAD_CONN_PARAM update existing connection by
dectecting the request is just for one connection, parameters already
exists and there is a connection.

Since this is a new behavior the revision is also updated to enable
userspace to detect it.
