Remove a KASSERT which will also trigger for perfectly valid combinations
of small maxsize and "large" (including BUS_SPACE_UNRESTRICTED) nsegments
parameters. Generally using a presz of 0 (which indeed might indicate the
use of bogus parameters for DMA tag creation) is not fatal, it just means
that no additional DVMA space will be preallocated.
