xen-netback: correct success/error reporting for the SKB-with-fraglist case
[ Upstream commit 3ede7f84c7c21f93c5eac611d60eba3f2c765e0f ] When re-entering the main loop of xenvif_tx_check_gop() a 2nd time, the special considerations for the head of the SKB no longer apply. Don't mistakenly report ERROR to the frontend for the first entry in the list, even if - from all I can tell - this shouldn't matter much as the overall transmit will need to be considered failed anyway.
