[PATCH] ARCNET: fix hard_header_len limit

[Michael Grzeschik]

The commit <9c7077622dd9> ("packet: make packet_snd fail on len smaller
than l2 header") adds the check for minimum packet length of the used l2.
For arcnet the hardware header length is not the complete archdr which
includes hard + soft header. This patch changes the length to
sizeof(arc_hardware).
