ixgbe: Fix ixgbe_tx_map error path
Commit e5a43549f7a58509a91b299a51337d386697b92c (ixgbe: remove
skb_dma_map/unmap calls from driver) looks to have introduced a bug in
ixgbe_tx_map. If we get an error from a PCI DMA call, we loop backwards
through count until it becomes -1 and return that.
The caller of ixgbe_tx_map expects 0 on error, so return that instead.
