net: lantiq: fix memory corruption in RX ring
[ Upstream commit c7718ee96dbc2f9c5fc3b578abdf296dd44b9c20 ]
In a situation where memory allocation or dma mapping fails, an
invalid address is programmed into the descriptor. This can lead
to memory corruption. If the memory allocation fails, DMA should
reuse the previous skb and mapping and drop the packet. This patch
also increments rx drop counter.
