Fix boot time interrupt storm on mec(4) by disabling DMA when stopping the
interface. Without this we are potentially freeing TX buffers that are in
use, plus we leave DMA enabled when rebooting. This leads to an interrupt
storm at boot time if we were receiving/transmitting network traffic whilst
shutting down.
ok miod@. Tested by jasper@.
