andrea.merello 348f7d4ade rtl8180: Add error check for pci_map_single return value in TX path
Orignal code will not detect a DMA mapping failure, causing the HW
to attempt a DMA from an invalid address.

This patch add the error check and eventually simply drops the TX
packet if we can't map it for DMA.
