For ISA DMA maps, the chipsets scatter/gather feature is used. As
such, the segments pointer in the DMA tag will always be NULL. In
bus_dmamap_load(), temporarily point the segments pointer in the
DMA tag to a local variable so that we don't dereference a NULL
pointer. Reset the segments pointer to NULL after calling the
callback function with it.
