Direct I/O user pages are forwarded to the backing files unchanged, so
the backing's DMA alignment requirement applies to them. Track the
backing file's dio_mem_align and advertise it as the zloop device's
dma_alignment if it is larger than the default so we advertise proper
limits and misaligned I/O is rejected early instead of being dispatched
to the backend.
