can: dummy_can: dummy_can_init(): fix packet statistics
[ Upstream commit c77bfbdd6aac31b152ee81522cd90ad1de18738f ]
The former implementation was only counting the tx_packets value but not
the tx_bytes as the skb was dropped on driver layer.
Enable CAN echo support (IFF_ECHO) in dummy_can_init(), which activates the
code for setting and retrieving the echo SKB and counts the tx_bytes
correctly.
