e100: fix dma error in direction for mapping
The e100 driver triggers BUG_ON(buf->direction != dir)
by doing pci_map_single(..., PCI_DMA_BIDIRECTIONAL)
and pci_dma_sync_single_for_device(..., PCI_DMA_TODEVICE).
Changing the DMA direction, especially with dmabounce will result
in unexpected behaviour.
