[golan] Use ETH_HLEN for inline header size

The driver does not correctly handle very short transmitted packets
such as EAPoL-Start where the entire DMA content lies within the
current send work queue entry inline header length of 18 bytes.

Fix by reducing the inline header length to the Ethernet frame header
length of 14 bytes.
