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.
