The test currently uses offsets and lengths which are multiples of
4K, but not multiples of 64K (or any other page size between 4Kb and
64Kb). This makes the reflink calls fail with -EINVAL because
reflink only operates on ranges that are aligned to the the
filesystem's block size.
Fix this by ensuring all ranges passed to the reflink calls are
aligned to 64K, so that the test works on any system regardless of
its page size. The test still fails without the corresponding
kernel fix applied [1] as it is supposed to.
