epic100: hamachi: yellowfin: Fix skb allocation size

Joel Soete reported oopses during pppoe over sundance NIC, caused by
a bug in skb allocation and dma mapping code, where skb_reserve()
bytes weren't taken into account. As a followup to the patch:
"sundance: Fix oopses with corrupted skb_shared_info" very similar
code is fixed here for three other drivers.
