[iwm] Fix iwm_dma_contig_free(). dma->map is always NULL here.

* When bus_dmamem_alloc is used, the bus_dmamap_t is usually set to NULL, so
  we were never actually freeing any dma memory allocations done via
  iwm_dma_contig_alloc(). So we should check dma->vaddr instead of dma->map here.

* Also, the dmamap is actually supposed to be invalidated as part of
  bus_dmamem_free(), so bus_dmamap_destroy() is never needed here.
