sky2: hand receive DMA mapping failures
If receive buffer mapping failed, then it was possible to get stuck with unmapped receive buffer in DMA ring. This would be an extremely rare condition because the driver had just released the map for the last receive so it should be able to get another map again (in soft-irq).
