xfs_io pwrite issues a series of block size writes, but there is no guarantee that the resulting extent(s) will be singular or contiguous. This behavior is acceptable, but the test is flawed in that it expects a single extent for a pwrite. Modify test to use actual blocksize for pwrite and reflink. Also modify it to accommodate pwrite and reflink that produce different mapping results.
