Log:
MFC amd64:
Consolidate all of the bounce tests into the BUS_DMA_COULD_BOUNCE flag.
Allocate the bounce zone at either tag creation or map creation to help
avoid null-pointer derefs later on. Track total pages per zone so that
each zone can get a minimum allocation at tag creation time instead of
being defeated by mis-behaving tags that suck up the max amount.
