When I did some bus_dma cleanup in r320528, I brought forward some sketchy WITNESS checks from the prior x86 busdma wrappers, instead of recognizing them as technical debt and just dropping them. Two of these were removed in r346351 and r346851, but one remains in bounce_bus_dmamem_alloc(). This check could be constrained to only apply in the BUS_DMA_NOWAIT case, but it's cleaner to simply remove it and rely on the checks already present in the sleepable allocation paths used by this function. While here, remove another unnecessary witness check in bus_dma_tag_create (the tag is always allocated with M_NOWAIT), and fix a couple of typos.
