When the target has sent its MESSAGE IN phase data to the initiator, it waits
for the initiator to release the ACK signal before disconnecting from the bus.
Send a MSG_ACC command to the ESP so that the initiator releases the ACK signal
to allow the target to disconnect, and also return the ASC back to the
disconnected state.
