tg3: Expand 4g_overflow_test workaround to skb fragments of any size.
The current driver assumes that an skb fragment can only be upto jumbo size. Presumably this was a fast-path optimization. This assumption is no longer true as fragments can be upto 32k. v2: Remove unnecessary parantheses per Eric Dumazet.
