Bump N_ELMCAN to avoid conflicts with future in-tree line disciplines.
We can't go higher than 29 because of NR_LDISCS == 30 in Linux 5.0.
We can't go lower than 28 because of N_NULL == 27 in Linux 5.0.

Avoid ldisc_ioctl() racing unregister_candev()
When getting the CAN interface's name via the SIOCGIFNAME ioctl,
elm->dev->name may no longer exist because the interface is being shut

Also, print the name of the interface to dmesg.
