There's no nede to allocate a DMA map just before calling bus_dmamem_alloc().
In fact, bus_dmamem_alloc() happily NULLs the dmat pointer passed in,
before replacing it with its own.
This fixes a MIPS crash when kldload'ing if_ath/if_ath_pci -
bus_dmamap_destroy() was passed in a NULL dmat pointer and was doing
all kinds of very bad things.
