can: at91/janz-ican3: replace snprintf() in show functions with sysfs_emit()
The sysfs show() functions must not use snprintf() when formatting the
value to be returned to user space.
Fix the following coccicheck warning:
| drivers/net/can/at91_can.c:1185: WARNING: use scnprintf or sprintf.
| drivers/net/can/janz-ican3.c:1834: WARNING: use scnprintf or sprintf.
|
| Use sysfs_emit instead of scnprintf or sprintf makes more sense.
