In a connection without outgoing traffic, conn->tx_num will remain 0.
In this case, conn->tx_pkt_med should be simply 0 without calculating
"conn->tx_bytes / conn->tx_num".
This was likely to happen, for example, when "btmon -w btsnoop.log"
was launched in the middle of a LE mouse connection, and a number of
incoming ACL Data RX were received as the mouse movements. When
running "btmon -a btsnoop.log", it would encounter this error.
