Prevent unnecessary verification of parity blocks while reading (#4683 )

* Prevent unnecessary verification of parity blocks while reading erasure
  coded file.
* Update klauspost/reedsolomon and just only reconstruct data blocks while
  reading (prevent unnecessary parity block reconstruction)
* Remove Verification of (all) reconstructed Data and Parity blocks since
  in our case we are protected by bit rot protection. And even if the
  verification would fail (essentially impossible) there is no way to
  definitively say whether the data is still correct or not, so this call
  make no sense for our use case.

xl: ReedSolomon code fix small file erasure bug. (#1431 )

For files less than 'dataBlocks', erasure encoding would fail
with short data due to a bug in the implementation itself.

Relax the error return, even a single byte can be properly
erasure coded without issues.

Fixes #1413
