    Make supports_direct_io work on 4096b sector size

    The current check uses an alignment of 512 bytes and will fail when the
    underlying device has sectors of size 4096 bytes, as is common e.g. for
    NVMe disks. So use an alignment of 4096 bytes, which is a multiple of
    512 bytes and thus will cover both cases.

    Conflicts:
            nova/privsep/utils.py
            - supports_direct_io() is still in
              nova/virt/libvirt/driver.py for this branch
