block: relax direct io memory alignment
Use the address alignment requirements from the block_device for direct
io instead of requiring addresses be aligned to the block size. User
space can discover the alignment requirements from the dma_alignment
queue attribute.
User space can specify any hardware compatible DMA offset for each
segment, but every segment length is still required to be a multiple of
the block size.
