gso: Fix support for linear packets
When GRO/frag_list support was added to GSO, I made an error which broke the support for segmenting linear GSO packets (GSO packets are normally non-linear in the payload). These days most of these packets are constructed by the tun driver, which prefers to allocate linear memory if possible. This is fixed in the latest kernel, but for 2.6.29 and earlier it is still the norm. Therefore this bug causes failures with GSO when used with tun in 2.6.29.
