[bb] fix bad blocks check for 64 bit

Browse source 
* 32 bit bad blocks check is too limited for large drives
  and result in erroneous computations
* 32 bit also means that 2TB would be absolute limit, which
  may be too low in case for USB HDD checks
* This fix makes bad blocks check and related calls 64 bit compliant
* also improve on bad block reports
