Bluetooth: Fix sending dummy buffer to kill invalid tx fiber

Browse source 
This fix prevents from sending dummy buffer to kill tx fiber
if this fiber didn't started.

Tx fiber is started during transition from BT_CONN_CONNECT state
(for outgoing connections) or BT_CONN_DISCONNECTED (incoming)
to BT_CONN_CONNECTED state.
So the only states that have tx fiber running are BT_CONN_CONNECTED
and BT_CONN_DISCONNECT and only transitions from these states
should be taken into account.
