    Description

      ost_brw_read set a number bytes as rq_status, that confuses check_set() function.
      that easy see if checksumming enabled.
      i found it's with testing solution to avoid panic in check_set() with request reorder and failed bulk read.
      attached patch solves both issues, but broke a request flags policy, and don't resend a bulk request so that can be short time solution, until check_set will cleared.
