XL/Erasure: Make bit-rot verification based on xl.json algo. (#2299)

Browse Source 
Currently `xl.json` saves algorithm information for bit-rot
verification. Since the bit-rot algo's can change in the
future make sure the erasureReadFile doesn't default to
a particular algo. Instead use the checkSumInfo.
