Subject: [PATCH net-next 09/37] can: dev: can_restart(): move debug message and stats after successful restart

Move the debug message "restarted" and the CAN restart stats_after_
the successful restart of the CAN device, because the restart may
fail.

While there update the error message from printing the error number to
printing symbolic error names.
