AOCL progress callback hardening

- BLIS uses callback function to report the progress of the
  operation. The callback is implemented in the user application
  and is invoked by BLIS.

- Updated callback function prototype to make all arguments const.
  This will ensure that any attempt to write using callback’s
  argument is prevented at the compile time itself.
