Properly handle alignment requests bigger that page size.
 - for now, alignments bigger that page size is allowed only for buffers
   allocated by bus_dmamem_alloc(), cover this fact by KASSERT.
 - never bounce buffers allocated by bus_dmamem_alloc(), these always comply
   with the required rules (alignment, boundary, address range).
