use qemu_blockalign consistently
Use qemu_blockalign for all allocations in the block layer. This allows increasing the required alignment, which is need to support O_DIRECT on devices with large block sizes. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
