can: fix ioctl function removal
Commit 60649d4e0af ("can: remove obsolete empty ioctl() handler") replaced the
almost empty can_ioctl() function with sock_no_ioctl() which always returns
-EOPNOTSUPP.
Even though we don't have any ioctl() functions on socket/network layer we need
to return -ENOIOCTLCMD to be able to forward ioctl commands like SIOCGIFINDEX
to the network driver layer.
This patch fixes the wrong return codes in the CAN network layer protocols.
