[PATCH 2/4] Bluetooth: Refuse peer L2CAP address reading when not connected

From: Johan Hedberg <redacted>

When we're not connected the peer address information is undefined. This
patch fixes the remote address getting to return a proper error in case
the state is anything else than BT_CONNECTED.
