Fixed access to unitialized memory when using unique HASH key

Browse Source 
Fixed the following issues:
- Call info with HA_STATUS_CONST to ensure that (key_info->rec_per_key)
  contains latest data
- Don't access rec_per_key if key_info->algorithm == HA_KEY_ALG_LONG_HASH
  is in this case the rec_per_key points to uninitialized data
- Cleaned up code to avoid some extra 'if' and to make things more readable
- Updated test cases that used 'old' rec_per_key values
