Bluetooth: Fix mgmt connected notification

Bluetooth: Fix mgmt connected notification

This patch fixes a regression that was introduced by commit
01528dc472626a01cf34945a2d00ae163b92a94a. In addition to BT_CONFIG,
BT_CONNECTED is also a state in which we may get a remote name and need
to indicate over mgmt the connection status. This scenario is
particularly likely to happen for incoming connections that do not need
authentication since there the hci_conn state will reach BT_CONNECTED
before the remote name is received.
