[BNX2]: Fix TSO problem with small MSS. 

Remove the check for skb->len greater than MTU when doing TSO.  When
the destination has a smaller MSS than the source, a TSO packet may
be smaller than the MTU at the source and we still need to process it
as a TSO packet.

Thanks to Brian Ristuccia <bristuccia@starentnetworks.com> for
reporting the problem.
