From: Vincent Mailhol <mailhol.vincent@wanadoo.fr>

TX timestamps were added to the can_put_echo_skb() function of can_dev
modules in [1]. However, can327 does not rely on that function and as
such does not offer TX timestamping.

Add a call to skb_tx_timestamp() in the can327_netdev_start_xmit()
function so that the module now supports TX software timestamps.

[1] commit 741b91f1b0ea ("can: dev: can_put_echo_skb(): add software
tx timestamps")
