Originally this test case was designed to work with only 4K sectorsize.
Now enhance it to work with any sector sizes and makes the following
changes:
Output file not to contain any traces of sector size.
Use max_inline=0 mount option so that it meets the requisite of non inline
regular extent.
Don't log the md5sum results to the output file as the data size vary by
the sectorsize.
