Currently the XFS log sector size defaults to the 512 bytes unless
explicitly overriden. Default to the device logical block size queried
by get_topology instead. If that is also 512 nothing changes, and if
the device logical block size is larged this prevents a mkfs failure
because the libxfs buffer cache blows up and as we obviously can't
use a smaller than hardware supported sector size. This fixes xfs/157
with a 4k block size device.
