If the rfcomm session has already sent DISC (thus in BT_DISCONN state), allow dlc opens to create a new session instead of trying to open a dlc in a closing session (and instead of returning an error). Allow multiple rfcomm sessions with the same endpoints as long as the existing sessions are either in BT_DISCONN or BT_CLOSED states. Fixes multi-second delays when running rctest -c on one station and rctest -r on the other.
