ftgmac100: Change interrupt status when a DMA error occurs
The model uses today the "Normal priority transmit buffer unavailable" interrupt status which it is not appropriate. According to the Aspeed specs, no interrupts are raised in that case. An "AHB error" status seems like a better modeling choice for all implementations since it is covered by the Linux kernel.
